Definition
The work-energy theorem states that the work done on an object is equal to the change in its kinetic energy. In other words, the net work done on an object is equal to the change in its energy of motion.
Related terms
Forces: Forces are interactions between objects that can cause changes in their motion. They play a crucial role in determining how much work is done on an object.
Kinetic Energy: Kinetic energy is the energy of motion possessed by an object due to its velocity. It is directly related to both mass and speed.
Potential energy refers to stored energy that an object possesses based on its position or condition. It can be converted into kinetic energy when released or acted upon by external forces.
