Question
Differentiate between mass and weight.
✓

Answer

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).
  5. The weight of a body is measured by a spring balance.
