Differences between mass and weight –
Mass :

1. The amount of matter contained in a body is called its mass.
2. The mass of a body is constant and does not change with place and position of the body.
3. The mass of a body can never be zero.
4. The SI unit of mass is kilogram (kg).
5. The mass of a body is measured by a simple beam balance or a physical balance.

Weight :

1. The weight of a body is the force with which it is attracted by the earth towards its centre.
2. The weight of a body depends on the force of gravity and thus changes from place to place.
3. The weight of a body can be zero if no force of gravity acts on the body.
4. The SI unit of weight is newton (N).
