Question

what is the difference between mass and weight of an object will the mass weight of an object on the earth be same as their values of Mars why

Answer 1

mass is not weight of object .
when gravity pushes mass it is called weight
no, because gravity of mars is not same as earth gravity
but mass can be same
and weight can be different

Answer 2

The mass of an object is the amount of matter present in it. It is same everywhere in the universe and is never zero. It is a scalar quantity and it's SI unit is kg. The weight of an object is the force with which the earth (or any other planet/ moon/ star) attracts it. It is directed towards the centre of the earth. The weight of an object is different at different places on the earth. it is zero at the earth's centre. It is a vector quantity and it's SI unit is the Newton (N). The magnitude of weight= mg.

The mass of an object will be the same on the earth and Mars, but the weight will not be the same because the value of g on Mars is different from that on the earth.
