Answer:

                 

Mass		Weight
1. The quantity of matter contained in a body is called the mass of the body.		1. The force with the earth attracts a body towards its centre is called the weight of the body.
2. It is a scalar quantity		2. It is a vector quantity.
3. The SI unit of mass is kg.		3. The SI unit of weight is newton (N).
4. The mass of an object remains the same everywhere, i.e., whether the object is on the earth on the moon or even in outer space.				4. Weight depends on its location.
5. The mass of an object can never be zero	5. The weight of an object can be zero. For example, in the inter ?planetary space and at the centre of the earth, where g = 0, the weight becomes zero.
6. It is measured by a beam balance (two-pan balance).			6. It is measured with a spring balance.
