What is the difference between them?

3. Mass is the total amount of matter or material in the object
Mass and weight
Mass is the total amount of matter or material in the object
E.g.
This is a wooden block. The total amount of wood in this block is 4 kg.
Then its mass is 4 kg
Whether it is on the Earth, on the Moon or in space, the mass is the same

4. Weight of an object is the pull on it by the Earth
Mass and weight
Weight of an object is the pull on it by the Earth
Thus, it is a force and is measured in newton (N)
Its weight = (4 X 10) N
= 40 N
E.g.
Do you know how
the weight changes,
if this block is
brought to the Moon?
The weight varies from place to place
