Can the work-energy theorem be applied to all types of motion?
Imagine a ball rolling down a hill. As it gains speed, its potential energy (stored energy due to its height) is converted into kinetic energy (energy of motion). This conversion is a direct result of the work done on the ball by the force of gravity. The work-energy theorem states that the net work done on an object is equal to the change in its kinetic energy. In other words, if you want to accelerate an object, you need to do work on it – and the amount of work done will determine the object's final speed.

Why the Work-Energy Theorem is Gaining Attention in the US
Work is the transfer of energy from one object to another, usually through a force applied over a distance. Energy, on the other hand, is a measure of an object's ability to do work. Think of it like pushing a car: the force you apply (work) is what gets the car moving, but it's the car's kinetic energy that allows it to maintain its speed.
