# What do we call the gravitational force between the earth and an object?

Gravitational force between the earth and an object:
The gravitational force between the earth and an object is known as the weight of the object. The weight of an object is the force of gravity acting on a body.

Formula for the weight of the object is:

$\boxed{W=mg}$

Here, the $W\rightarrow$ weight of the object

$m\rightarrow$mass of the object

$g\rightarrow$acceleration due to gravity

SI unit of weight:

The SI unit of the weight of an object is $kg-m/s^2$ or Newton.

Direction of the weight of an object:
Based on the above discussion we come to know that weight is a gravitational force acting between the earth and an object. Due to this gravitational force, the earth pulls any object towards its surface. Therefore, the direction of the weight of the object is towards the earth's center. Weight is a vector quantity.

The weight of an object varies from place to place:
The weight of an object varies from one place to another place. This is because the weight of any object is directly proportional to the value of gravitational accelerattion$(g)$ and the value of $(g)$ is different at different places.
