A:

Hi,

Mass:The mass of a body is the quantity of matter contained in it. The SI unit is kilogram. The mass of the body is constant and does not change from place to place.

Weight: The force with which an object is attracted towards the earth is the weight of that object.

It is written as . Its unit is newton (N).

As g is constant at a place, W is directly proportional to the mass of the object. 

The weight of the body changes from place to place and is not constant.
