# What does gravity mean?

Jan 12, 2016

Force of attraction between particles that have mass.
REMEMBER : it is also repulsive in nature but that is caused due to dark matter or dark energy.
.

#### Explanation:

The force of gravity 'felt' between two particles is directly proportional to the product of the masses of the two particles, and inversely proportional to the square of the distance between them.

$F = \frac{G {m}_{1} {m}_{2}}{r} ^ 2$

Where:

• $G$ is the gravitational constant
• ${m}_{1}$ and ${m}_{2}$ are the masses of the two particles
• $r$ is the distance between the two particles

ALSO,As per Einstein when between two bodies some kind of energy is uniformly distributed , it causes repulsive gravity
