Question

What is the difference between mass and weight of an object.will the mass and weight of an object on the eart be same as their value on mars? Why?

Answer 1

Mass is the volume of an object multiplied with density but weight is a force
Dimensions of mass = KG
Dimensions of weight = Newton = KgM/sec
Weight is mass x gravity

Answer 2

mass means total matter contained in a body where as weight force of gravity working on a body mass of the object will be same but the weight will not be same because gravity in mars is different than it is in earth.
