Question

2. State and explain work energy principle. Mention any three examples for it ​

Answer 1

Explanation:

a car moving in with constant velocity is accelerated. Hence there is an increase in velocity. So kinetic energy is increased by the positive work done by the engine. 2) A ball dropped from a height H. Work done by gravity increases the velocity of the ball and thus kinetic energy increases.
