Question
Explain the difference between potential energy and kinetic energy.
Advertisements
Solution
| S. No. | Potential Energy | Kinetic Energy |
| 1. | It is possessed by a body by virtue of its configuration and position. | It is possessed by a body by virtue of its motion. |
| 2. | It exists in several forms, including gravitational potential energy and electric potential energy, but work is not completed until it is converted into kinetic energy. | It only exists in one form and does not need to be converted into another in order to perform tasks. |
| 3. | Gravitational potential energy = mgh | Kinetic energy = `1/2 mv^2` |
| 4. | Potential energy can be negative. | Kinetic energy cannot be negative. |
| 5. | Example: A book kept on a shelf has potential energy. | Example: A moving car possesses kinetic energy. |
