Answer
Kinetic energy | Potential energy | |
1. | Kinetic energy of a body is due to motion of the body. | Potential energy is due to position or change in shape of the body. |
2. | Kinetic energy is zero for a still body. | Potential energy may or may not be zero for a still body. |
3. | Kinetic energy of a body is directly proportional to its speed | Potential energy is directly proportional to the height to which the body is above the ground. |
