Question

Explain what is gravitation?

Answer 1

Gravitation:

1. Gravitation is an attractive force.
2. Gravitation is responsible for attracting two bodies with respective masses towards each other.
3. Therefore, every particle made up of matter exerts a gravitational force on every other particle in the universe.
4. Gravitation does not require any medium.
5. If $m_1$ and $m_2$ are the masses of the two bodies and $r$ is the distance between them, then according to the universal law of gravitation, the gravitational force exerted by these two masses towards each other is, $F=G\frac{m_1{m}_2}{r^2}$ where $G$ is the universal gravitational constant.
