Differences between mass and weight
March 20, 2018
S.N | Mass | Weight |
1. | The amount of matter contained in a body is called mass. | The force by which earth attracts or pull objects towards its center is called weight. |
2. | It remains always constant regardless of the location in universe. | It varies from place to place. |
3. | It is measured by ordinary or beam balance. | It is measured by spring balance. |
4. | It is measured in grams or kilograms. | It is measured in newton. |
5. | It has only magnitude but no direction so scalar quantity. | It has both magnitude and direction so called vector. |
6. | Mass of a body can never be zero. | Weight can be zero if gravity does not act on the body. |
7. | Mass of a moving body can be calculated by using formula: F=m/a. | Weight of a body can be calculated by using formula: w=m.g. |
8. | It is closely related to inertia. | It is closely related to gravity. |
9. | It is denoted by ‘m’ or ‘M’. | It is denoted by ‘w’. |
