# What is Gravitational force?

The universal force of attraction acting between all matter is the gravitational force. It is by far the weakest known force in nature.

### Definition

Gravitational force is defined as a force of attraction with which all the physical bodies attract each other. It is a non-contact type of force.

Formula

The gravitational force also has the formula like other forces. The gravitational force formula is given below

$$\begin{array}{l}F=G\frac{m_{1}m_{2}}{r^{2}}\end{array}$$

Where,

Where,

F is the gravitational force between two bodies

G is universal gravitational constant,
m1 is the mass of the first body
m2 is the mass of the second body
r is the distance between the centres of two bodies
