# Why is mass density more important than weight density?

## Question:

Why is mass density more important than weight density?

## Acceleration Due to Gravity;

When two bodies which are having some mass attract each other then do so because of the gravitational force between them and since a force will cause an acceleration of the object towards each other thus, a lighter body will be accelerated towards the heavier body.

The acceleration of the body caused due to gravitational force is known as acceleration due to gravity.
