उत्तर
- The energy of a body in motion is called its kinetic energy.
- It is defined as follows:
Kinetic energy of a body is the energy possessed by it due to its state of motion. Actually, it is the work done on the body bringing it to the state of motion. - In short form, it is written as K.E. or K.
- Example: In a swinging pendulum moving to and fro, the bob has the kinetic energy.
