Question

differentiate between A) Mass and weight. B)Gravity and gravitation

Answer 1

There is a basic difference, because massis the actual amount of material contained in a body and is measured in kg, gm, etc. Whereas weight is the force exerted by the gravity on that object mg. Note that mass is independent of everything but weight is different on the earth, moon, etc.

Answer 2

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. Mass is denoted using m or M.

Weight is the measure of the amount of force acting on a mass due to the acceleration due to gravity.

Gravity and Gravitation

Gravity is the universal phenomenon by which the objects in the universe exert a force on each other. The force exerted is called gravitational force which is always attractiveThe force between the two charges (Electrostatic force) can be both attractive or repulsive, unlike gravity which is always attractive. This gravitational force depends upon the masses of two bodies and the distance between their centre of masses.
