Question

Explain relation between work and energy

Answer 1

There is a strong connection between work and energy, in a sense that when there is a net force doing work on an object, the object's kinetic energy will change by an amount equal to thework done: Note that the work in this equation is the work done by the net force, rather than the work done by an individual force.

Answer 2

The relation between work and energy is very complex. Work needs energy and without energy no work can be done.
