Newton`s 3rd Law Notes
... When a cannon fires a cannonball, the cannon pushes on the cannonball and the cannonball pushes back on the cannon with equal force. This is why the cannon recoils. The cannonball moves with much greater acceleration than the cannon, because the cannonball’s mass is much less than the mass of the ca ...

... If you stop pushing an object, does it stop moving? Only if there is friction! In the absence of any net external force, an object at rest will remain at rest. In the absence of any net external force a moving object will keep moving at a constant speed in a straight line. This is also known as the ...

... Thus, in uniform circular motion there must be a net force to produce the centripetal acceleration. The centripetal force is the name given to the net force required to keep an object moving on a circular path. The direction of the centripetal force always points toward the center of the circle and ...

... learned that force (of course, unbalanced if only one force) causes a changing motion, i.e. non-uniform motion. Non-uniform motion can lead to motion (as an object starts moving, there must be a change in motion), but whenever an unbalanced force is applied to an object there is a changing motion. c ...
