प्रश्न
Differentiate between the potential energy (U) and the kinetic energy (K).
अंतर स्पष्ट करें
उत्तर
| Potential energy (U) | Kinetic energy (K) |
| 1. The energy possessed by a body by virtue of its specific position or changed configuration is called potential energy. | 1. The energy possessed by a body by virtue of its state of motion is called kinetic energy. |
| 2. Two forms of potential energy are gravitational potential energy and elastic potential energy. | 2. Forms of kinetic energy are translational, rotational and vibrational kinetic energy. |
| 3. Example: A wound up watch spring has potential energy. | 3. Example: a moving car has kinetic energy. |
