10 Examples of Mechanical Energy in Everyday Life,
The bowling ball consists of some amount of energy in the form of kinetic energy as soon as it starts rolling towards the target. Due to this energy, the ball has the ability to do work on the pins. When the ball hits those target pins, it (ball) applies force (in the form of mechanical energy) and displaces them, hence, causing work to be done.
