Question

What are the difference between mass, weight, volume and density? Could you please give a definition for these too.

Answer 1

The mass of the mass of a body is the amount of matter contained in it and it is measured in kilograms or grams.

The weight of the body is the measure of how hard the earth is pulling on it it is measured in newtons and it is calculated by the formula w = mg where g is the acceleration due to gravity.

And volume is this space that the body takes.

Density is the amount of matter contained in a unit volume of that body.
