What are the differences between the mass of an object and its weight?


The quantity of matter in a body is called mass.

The force with which earth attracts objects towards center is called weight.

Weight and mass are entirely different entities. The mass of an object on the earth will be same universally as the mass is the amount of matter present in the body. While, the weight of an object will change on earth and other planets. 

Difference between mass and weight



The measure of the amount of matter in a body.

The measure of the amount of force acting on a mass due to acceleration due to gravity.

Mass = volume × density

Weight = mass × acceleration due to gravity

The SI unit of mass is Kilogram (Kg).

The SI unit of weight is Newton (N).

It is a scalar quantity.

It is a vector quantity.
