Rainbow 🌈 mind map Potential energy
Definition: The energy possessed due to its state of rest or position of a body.
Quantity: derived quantity
Units: CGS- erg , SI- joule
Formula: G.P.E = mgh
Types:
- Elastic potential energy ( the energy stored when the size or shape of the body is changed)
- Gravitational potential energy ( the energy when body is taken to a height above the ground)
Transfer to other form:
- P.E does not directly change into any other form of energy except the kinetic energy when it is put to use.
Related to work:
P.E is equal to the work done on the body to bring it to that state of rest or position.
