Kinetic energy: “Energy possessed by a body by virtue of its motion.”
Examples :
1. A bullet though of very small mass but moving with high speed and hence kinetic energy can peneterate a body.
2. Running water of the river due its kinetic energy can rotate a turbine to produce electricity.
3. A trunk running at high speed possesses kinetic energy and when hits a body can damage it.
4. A shooting arrow possesses kinetic energy. 5. Blowing wind possesses K.E.
