Question

state and explain work energy principle. mention any 3 examples for it​

Answer 1

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. 3) Brakes are applied in a motor bike and it comes to rest after a few seconds.
