what is the difference between mass and weight?

The amount of substance in a structure (atoms, for example) determines its mass; more mass indicates more inertia, because there is more to move. (This is Isaac Newton's concept of mass, which he developed in the 19th 1600s and is the foundation of his famous conservation of momentum.) It's not entirely accurate at really high speeds, when Albert Einstein's 20th-century theory of special relativity is necessary, but it's fine in most instances.)
The quantity of descending force exerted by gravity force is measured by its weight. The strength of gravity's pull rises with the mass of the object: the more inertia it has, the stronger it pulls. Gravity is 9.8 newtons per kilogramme on Planet's surface.

Difference between mass and weight-

1.Material present in body is called mass or weight is the force exerted by gravity on an object.

2. Mass si unit is kg or weight si unit is Newton.

3. Mass never be changed while weight change due to gravity from place to place.

4. mass of an object can never be 0 while weight can be zero if gravity is 0.

5. Mass is a scalar quantity or weight is a vector quantity.

6.Mass can be determined by ordinary balance or weight can be measured by spring balance.
