... This tells us two things. One is that again, the speed at which an object falls doesn’t depend on its mass. The second is that if the acceleration due to gravity were different (say, on another planet) you’d weigh a different amount. These two concepts are the basis of this exercise. Additional Back ...

... Particle System Consider an isolated system with two particles that do not have any external forces exerting on it. What is the impact of Newton’s 3rd Law? If particle#1 exerts force on particle #2, there must be another force that the particle #2 exerts on #1 as the reaction force. Both the forces ...

... NEWTON’S FIRST LAW: Consider an object on which no net force acts. If the body is at rest, it will remain at rest. If the body is moving with constant velocity it will continue to do so. Note that forces may still act on the object but the net (resultant) must be zero. Newton’s first law is sometime ...

... equilibrium- when two or more forces act concurrently (at the same time) on an object, and their vector sum is zero. An object in equilibrium has no acceleration because the forces on it are balanced. According to Newton's 1st law, this means that the object is “not moving” or is moving at constan ...
