प्रश्न

Explain the difference between potential energy and kinetic energy. 

अंतर स्पष्ट करें

उत्तर

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. Eg: A book kept on a shelf has potential energy. Eg: A moving car possesses kinetic energy.
