Gravitation ​

Answer 1

Answer:

a

The difference between mass and weight is that mass is the amount of matter in a material, while weight is a measure of how the force of gravity acts upon that mass. Mass is the measure of the amount of matter in a body. ... Weight usually is denoted by W. Weight is mass multiplied by the acceleration of gravity (g)

b

Mass of an object remains same irrespective of its location and motion in classical mechanics. So mass will be same on both Mars and Earth. However the weight is measure of force exerted by a body on the ground. Hence this value will be affected by the local value of gravitational acceleration.
