Question

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

Answer 1

Gravitational force:

1. The weight of an object is the gravitational force between it and the earth.
2. The force of gravity acting on a body is measured by weight.
3. The weight formula is $W=mg$. Here $m$ is mass of the body and $g$ is the gravitational acceleration.
4. Because weight is a force, Its SI unit is also the same as that of force; Newton is the SI unit of weight (N).
5. Weight can be nil. If no gravity acts on an object in space, its weight becomes zero.
6. Weight is a vector quantity.
7. It has magnitude and is aimed at the centre of the Earth.
