Question
What is the difference between gravitational potential and gravitational potential energy?
Solution
Gravitational potential | Gravitational potential energy |
Amount of work done required to bring unit mass from infinity to the distance r. | Amount of work done in bringing the body from infinity to a given point in the gravitational field of other body. |
It is given by, V(r) = `-"Gm"_1/"r"` | It is given by, U(r) = `-("Gm"_1"m"_2)/"r"` |
