Detailed explanation-1: -The concepts of work and energy are closely tied to the concept of force because an applied force can do work on an object and cause a change in energy. Energy is defined as the ability to do work.
Detailed explanation-2: -Energy :The ability to do work or cause a change.
Detailed explanation-3: -Kinetic energy Moving objects are capable of causing a change, or, put differently, of doing work.
Detailed explanation-4: -Energy is required to do work and the basic SI unit of energy is the joule, the amount of energy required to exert a force of 1 Newton through a distance of 1 meter (1 joule = 1 newton meter).
Detailed explanation-5: -The work-energy theorem states that the net work done by the forces on an object equals the change in its kinetic energy.
