Question
State the law of conservation of energy. Hence describe the relationship between work and energy.
Solution
The law of conservation of energy states that energy can neither be created nor destroyed.
It can only be converted from one form to another.
Work and energy are correlated. Whenever work is done, the object that does work loses energy and the object on which work is done, gains some energy.
For example, when we kick a ball, we lose some energy and the ball gains an equal amount of energy. The energy gained by the ball makes it to move.
