... 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 ...

Abstract Newton’s second law makes references to the forces exerted on an object, which are capable of producing a change in its velocity and, likewise, in its acceleration.

... What if the acceleration of the object is non-zero? Sometimes, we do not know the magnitude of the acceleration, particularly before we have solved the problem! Often we want to solve for the acceleration of an object. Even if we do not yet know the magnitude of the acceleration, sometimes we know i ...

... but aligned with the radial direction. That’s because we want to determine the component of any force or forces that may act as a centripetal force. We are ignoring friction so the only two forces to consider are the weight mg and the normal force FN . As can be seen only the normal force has an inw ...
