This physics video tutorial explains how to find the net force acting on an object in the horizontal direction. Problems include kinetic frictional force, calculating acceleration using force & mass, and kinematics problems such as finding the distance travel, calculating the final speed or the time it takes to travel. A knowledge of free body diagrams and a basic understanding of newton's laws of motion is required such as newton's 2nd law of motion. This video contains plenty of examples and practice problems as well as the formulas & equations needed to solve it.

This video follows Forces 1-3. This tutorial is about adding forces to get a net force. It includes net force, free body diagrams (FBD), and force addition. http://www.BCLearningNetwork.com. 0:00at this point we've learned a lot about forces forces are pushes or pulls on an 0:07object forces can cause changes in motion forces can speed up an object or 0:15slow it down forces can be contact forces such as applied forces or 0:23friction forces but forces can also be non-contact such as gravity or magnetic 0:31for Asus forces are most commonly measured in Newtons and one Newton is 0:39about the way to the medium Apple pushing forces also called compression 0:46can be measured using a floor scale while pulling forces also called tension 0:54can be measured using a spring scale in this tutorial we're going to learn about 1:01net force that is the addition of more than one force so consider that you 1:09could push on an object with a force of one hundred and and if your friend can 1:15push with a force of sixty Newton's then how much force can you both apply to the 1:22box if you both push well first let's draw little picture of the object with 1:29both forces being represented by arrows in the direction of the force the 100 1:37numero that's your push is shown to the right here then we have your friends 16 1:45you narrow and we'll try it a little bit shortages show that it is a smaller 1:50force and so here we are with the object and the forces on it and we call this 1:57little sketch a free body diagram which we often just radius FBD 2:05free body diagram is used to make a situation look really simple so now 2:12let's consider what 2:13is happening here by referring to a free body diagram now since you're both 2:19pushing in the same direction that is the force arrows on the free body 2:24diagram are both in the same direction we could just add the forces together 2:30and determine that the box receives a total applied force of one hundred and 2:37sixteen Newton's to the right so we'd say that the net force on the object is 2:45one hundred and sixty Newton's to the rate they change in motion of the box 2:50would be as if there was just a single force of one hundred and sixty Newton's 2:57to the right 3:01another example what if your friend was pushing this time in the opposite 3:06direction of you so they're pushing on the other side of the box so you're 3:10pushing with a hundred and to the right and they're pushing the other way with 3:1516 to the left then what happens 3:19well let's first run free body diagram and this time the airless would be going 3:26in opposite directions 3:28your force is going to the rate again but in this case your friends force is 3:33to the left a little bit smaller again so your sources are opposing each other 3:40so they wouldn't add the same anymore with your friends force would be tense 3:46laying out part of your source so you're pushing harder so then met applied force 3:52experienced by the box is your source 100 Newton's minus your friends for 16 4:01IANS which equals forty Newton's to the right so we would say that then met 4:09forests on the object is 40 mutants to the right that change in motion of the 4:16object would be as if there was just a single source of forty Newton's to the 4:22right 4:24one more example what if you were pushing to the rates and your friend was 4:29pushing to the left but we also had a frictional force that is maybe your 4:35object was on a rough concrete floor making it hard to move the friction 4:40force in this case is 40 Newton's to the left 4:45opposing the motion of the box so let's first maker free body diagram so in this 4:52case we have your force pushing right hundred Newtons and then your friends 4:57force pushing left 16 innings now the frictional force is opposing the motion 5:02and so it's going left at forty Newtons and seek insured along the surface here 5:08where it's apply now adding up for a net forest well we have one hundred and 5:14going rights minus sixty Newton's going left and then another 40 news going left 5:22which we have to subtract so we add all that up and we have 100 miners 60-40 and 5:31that equals zero so what does that mean a net force of 0 is almost like having 5:37no force acting on the object at all the emotion doesn't change we would say that 5:45the forces in this case our balance that is they all add up to zero or that the 5:53net force is zero which is a very interesting case 6:00in this tutorial we learn how to consider more than one for us on a

Interaction Forces
 
06:28
040 - Interaction Forces In this video Paul Andersen explains how forces on an object always require another object. An object cannot exert a force on itself. If net forces on an object are balanced the object will remain at rest or move with a constant velocity. However if the net forces are unbalanced the object will accelerate in the direction of the net force. Do you speak another language?

Balanced and Unbalanced Forces | Forces and Motion | The Fuse School
 
02:35
How do we find out whether the forces acting on an object are balanced or unbalanced? Learn in this video from the "Forces and Motion" chapter of the Virtual School GCSE / K12 Physics. 00:00:00,689 -- 00:00:08,109 Balanced forces. The famous English 00:00:05,140 -- 00:00:10,690 scientist Sir Isaac Newton who lived 00:00:08,109 -- 00:00:13,570 between the 17th and 18th century 00:00:10,690 -- 00:00:15,550 devised three laws of motion. The first 00:00:13,570 -- 00:00:17,199 law states that if all the forces acting 00:00:15,550 -- 00:00:20,019 on an object are balanced, 00:00:17,199 -- 00:00:22,689 there will be no acceleration; meaning 00:00:20,019 -- 00:00:25,359 either constant velocity or the object 00:00:22,689 -- 00:00:27,730 remaining stationary but, what do we mean 00:00:25,359 -- 00:00:31,269 by balanced forces? Let's look at the 00:00:27,730 -- 00:00:33,280 example of a horse. The first force we 00:00:31,269 -- 00:00:35,650 will consider is the force of gravity, 00:00:33,280 -- 00:00:38,500 this acts towards the center of the 00:00:35,650 --00:00:41,770 earth the size of the force of gravity 00:00:38,500 -- 00:00:44,230 is the horses weight. An arrow is drawn 00:00:41,770 -- 00:00:46,570 downwards from the horse towards the 00:00:44,230 -- 00:00:48,790 center of the earth. If this were the 00:00:46,570 -- 00:00:51,580 only force acting on the horse it would 00:00:48,790 -- 00:00:53,770 sink into the ground as this is not the 00:00:51,580 -- 00:00:56,980 case, there must be a force opposing the 00:00:53,770 -- 00:01:00,180 force of gravity and arrows drawn in the 00:00:56,980 -- 00:01:02,980 opposite direction but equal in size. 00:01:00,180 -- 00:01:06,310 This force is called the reaction force. 00:01:02,980 -- 00:01:08,830 As the reaction force is the same size 00:01:06,310 -- 00:01:11,140 but acts in the opposite direction to 00:01:08,830 -- 00:01:15,010 the horses weight these two forces are a 00:01:11,140 -- 00:01:17,740 balanced pair of forces. There are other 00:01:15,010 -- 00:01:20,140 forces acting on the horse, the horse is 00:01:17,740 -- 00:01:22,590 moving forward and therefore there must 00:01:20,140 -- 00:01:25,720 be a driving force from the horse's legs. 00:01:22,590 -- 00:01:28,090 The driving force though is opposed by 00:01:25,720 -- 00:01:29,770 forces trying to slow the horse down and 00:01:28,090 -- 00:01:32,830 if the horse is traveling at a constant 00:01:29,770 -- 00:01:35,320 velocity, the force of friction and air 00:01:32,830 -- 00:01:37,240 resistance are equal in size but 00:01:35,320 -- 00:01:41,500 opposite in direction to the driving 00:01:37,240 -- 00:01:43,890 force the driving force is now balanced 00:01:41,500 -- 00:01:47,409 by friction and air resistance a 00:01:43,890 -- 00:01:50,170 balanced pair of forces and the horse 00:01:47,409 -- 00:01:53,380 now travels a constant velocity. If 00:01:50,170 -- 00:01:55,450 though the horse accelerates the driving 00:01:53,380 -- 00:01:58,720 force must be greater than friction and 00:01:55,450 -- 00:02:00,880 air resistance the driving force is now 00:01:58,720 -- 00:02:01,780 no longer balanced by friction and air 00:02:00,880 -- 00:02:06,250 resistance; 00:02:01,780 -- 00:02:08,740 these forces are now unbalanced. So in 00:02:06,250 -- 00:02:11,530 summary when the forces are balanced on 00:02:08,740 -- 00:02:13,960 an object the object will either remain 00:02:11,530 -- 00:02:17,650 stationary or travel at 00:02:13,960 -- 00:02:19,860 velocity when the forces are unbalanced 00:02:17,650 -- 00:02:22,900 the object will either accelerate 00:02:19,860 -- 00:02:27,840 meaning an increase in velocity or 00:02:22,900 -- 00:02:27,840 decelerate meaning a decreasing velocity At Fuse School, teachers and animators come together to make fun & easy-to-understand videos in Chemistry, Biology, Physics, Maths & ICT.

This physics video tutorial explains how to find the normal force on a scale in a typical elevator problem. It discusses how to calculate the apparent weight of a person when the elevator is at rest, moving upward with constant speed, downward with constant velocity, accelerating upward or downward. It uses free body diagrams and net force calculations to find the apparent weight shown on a scale which is equivalent to the normal force of the scale on the person.

What is a Force?
 
03:40
Force is a central concept in physics. By analysing the forces on an object, its resulting motion can be determined. But what exactly is a force? The word force is used in everyday language in a variety of contexts, only some of which reflect the scientific definition of force. In this video, people at Victoria Park in Sydney are interviewed on their ideas of force and the forces that act on them.

Interactive Graphics for Wind Tunnel Testing 1974 USAF Air Force Systems Command FR-239

more at: http://scitech.quickfound.net/aviation_news_and_search.html "USE OF INTERACTIVE GRAPHICS TO IMPROVE EFFICIENCY OF WIND TUNNEL TESTING PROGRAMS" AFSC STAFF FILM REPORT 239 (USAF Film FR-1412). Public domain film from the US National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). http://creativecommons.org/licenses/by-sa/3.0/ https://en.wikipedia.org/wiki/Wind_tunnel A wind tunnel is a tool used in aerodynamic research to study the effects of air moving past solid objects. A wind tunnel consists of a tubular passage with the object under test mounted in the middle. Air is made to move past the object by a powerful fan system or other means. The test object, often called a wind tunnel model is instrumented with suitable sensors to measure aerodynamic forces, pressure distribution, or other aerodynamic-related characteristics. The earliest wind tunnels were invented towards the end of the 19th century, in the early days of aeronautic research, when many attempted to develop successful heavier-than-air flying machines. The wind tunnel was envisioned as a means of reversing the usual paradigm: instead of the air standing still and an object moving at speed through it, the same effect would be obtained if the object stood still and the air moved at speed past it. In that way a stationary observer could study the flying object in action, and could measure the aerodynamic forces being imposed on it. The development of wind tunnels accompanied the development of the airplane. Large wind tunnels were built during the Second World War. Wind tunnel testing was considered of strategic importance during the Cold War development of supersonic aircraft and missiles. Later on, wind tunnel study came into its own: the effects of wind on man made structures or objects needed to be studied when buildings became tall enough to present large surfaces to the wind, and the resulting forces had to be resisted by the building's internal structure. Determining such forces was required before building codes could specify the required strength of such buildings and such tests continue to be used for large or unusual buildings. Still later, wind-tunnel testing was applied to automobiles, not so much to determine aerodynamic forces per se but more to determine ways to reduce the power required to move the vehicle on roadways at a given speed. In these studies, the interaction between the road and the vehicle plays a significant role, and this interaction must be taken into consideration when interpreting the test results. In an actual situation the roadway is moving relative to the vehicle but the air is stationary relative to the roadway, but in the wind tunnel the air is moving relative to the roadway, while the roadway is stationary relative to the test vehicle. Some automotive-test wind tunnels have incorporated moving belts under the test vehicle in an effort to approximate the actual condition, and very similar devices are used in wind tunnel testing of aircraft take-off and landing configurations. The advances in computational fluid dynamics (CFD) modelling on high speed digital computers has reduced the demand for wind tunnel testing. However, CFD results are still not completely reliable and wind tunnels are used to verify CFD predictions...

Newton's Laws Of Motion (2) : Force, Mass And Acceleration
 
06:25
ESA Science - Newton In Space (Part 2): Newton's Second Law of Motion - Force, Mass And Acceleration. Newton's laws of motion are three physical laws that form the basis for classical mechanics. They have been expressed in several different ways over nearly three centuries. --- Please subscribe to Science & Reason: • http://www.youtube.com/Best0fScience • http://www.youtube.com/ScienceMagazine • http://www.youtube.com/FFreeThinker --- The laws describe the relationship between the forces acting on a body and the motion of that body. They were first compiled by Sir Isaac Newton in his work "Philosophiæ Naturalis Principia Mathematica", first published on July 5, 1687. Newton used them to explain and investigate the motion of many physical objects and systems. For example, in the third volume of the text, Newton showed that these laws of motion, combined with his law of universal gravitation, explained Kepler's laws of planetary motion. --- Newton's Second Law of Motion: A body will accelerate with acceleration proportional to the force and inversely proportional to the mass. Observed from an inertial reference frame, the net force on a particle is equal to the time rate of change of its linear momentum: F = d(mv)/dt. Since by definition the mass of a particle is constant, this law is often stated as, "Force equals mass times acceleration (F = ma): the net force on an object is equal to the mass of the object multiplied by its acceleration." History of the second law Newton's Latin wording for the second law is: "Lex II: Mutationem motus proportionalem esse vi motrici impressae, et fieri secundum lineam rectam qua vis illa imprimitur." This was translated quite closely in Motte's 1729 translation as: "LAW II: The alteration of motion is ever proportional to the motive force impress'd; and is made in the direction of the right line in which that force is impress'd." According to modern ideas of how Newton was using his terminology, this is understood, in modern terms, as an equivalent of: "The change of momentum of a body is proportional to the impulse impressed on the body, and happens along the straight line on which that impulse is impressed." Motte's 1729 translation of Newton's Latin continued with Newton's commentary on the second law of motion, reading: "If a force generates a motion, a double force will generate double the motion, a triple force triple the motion, whether that force be impressed altogether and at once, or gradually and successively. And this motion (being always directed the same way with the generating force), if the body moved before, is added to or subtracted from the former motion, according as they directly conspire with or are directly contrary to each other; or obliquely joined, when they are oblique, so as to produce a new motion compounded from the determination of both." The sense or senses in which Newton used his terminology, and how he understood the second law and intended it to be understood, have been extensively discussed by historians of science, along with the relations between Newton's formulation and modern formulations. • http://en.wikipedia.org/wiki/Newton%27s_laws_of_motion .

Physics Resultant Force when the Angiles
 
02:24
Physics Resultant Force when the Angiles Resultant force refers to the reduction of a system of forces acting on a body to a single force and an associated torque. The choice of the point of application of the force determines the associated torque. The term resultant force should be understood to refer to both the forces and torques acting on a rigid body, which is why some use the term resultant force-torque.
