Question

what is the difference between mass and weight

Answer 1

mass is constant, usually refers to the amount of matter.

weight=mg

where m=mass and g=gravity

Answer 2

mass doesn't change whether you are on earth, the moon or on saturn.

weight is dependent on the amount of force exerted by gravity.

Answer 3

Mass is a measure of inertia. Weight is a particular type of force that acts on mass due to gravity.

Answer 4

Mass is a characteristic of an object. The weight is the force that a planet for example, does to the object.

Mass body with 0 velocity is unchangeable, Its weight depends of the planet where it is and is given by :

Weight= mass x planet acceleration

or

W=m.g
