Distinguish between mass and weight of a body. When does a body experience weightlessness?
Answer :
The mass of a body is a measure of its inertia. It is independent of the acceleration due to gravity at a place.
The weight of a body is the force with which it is attracted to the earth. It is directly proportional to the acceleration due to gravity. Thus, we feel heavier on earth than the moon.
We experience weightlessness during free fall because we have no support to feel our weight.
