difference between mass and weight.
Answers
Explanation:
Mass is the scalar quantity .It has magnitude.
weight is a vector quantity.It has magnitude and is directed toward the center of the Earth or other gravity well.
The unit of mass is kg .
The unit of weight is N.
Mass can never be zero.
Weight can be zero if no gravity acts upon an object, as in space.
Mass does not change according to location.
Weight varies according to location.
1. Mass of a body is quantity of matter in the body.
Weight of a body is the force with which it is attracted towards the centre of the Earth.
2. Mass is the measure of inertia of the body. So its SI unit is kg.
Weight is a kind of force. W=mg. So its SI unit is N.
3. Mass is a scalar quantity.
Weight is a vector quantity. Its direction is always towards the centre of the Earth.
4. Mass is constant.
Weight varies from place to place.
5. Mass can never be zero.
At the centre of the Earth, weight is zero.
6. Mass is measured using a beam balance.
Weight is measured using a spring balance.
