# Universal Law of Gravitation

- Every particle attracts every other particle with a force proportional to the product of their masses and inversely proportional to the square of the distance between them
- Gravitational attraction between two objects
- Inverse square law

## Formula

- $F_{gravity} = G \frac{M_1M_2}{R^2}$
- $F_{gravity}$ is the force of gravity between two objects
- $M_1$ and $M_2$ are the masses of two objects
- $R$ is the separation of those objects
- $G$ is the
*universal gravitational constant*
