When an object is moving, it possess an energy and such energy is called kinetic energy. To know more about kinetic energy, click here. Kinetic energy is explained along with their pictures here.
Kinetic energy can be seen in daily life. Some of the example that can be seen in normal life are explained below.
When you hit a nail on a wall with a hammer with a force, thereby, with a velocity as shown in the picture, the kinetic energy of the hammer helps you to drive the nail into the wall.
Another example of kinetic energy is billiards which is shown in the picture. In billiards, a player gives the cue ball kinetic energy when he strikes the ball with the cue. As the ball rolls, it exerts kinetic energy.
