A person on the moon experiences gravitational force but same person experiences weightlessness in an artificial satellite of earth. Explain.

Text Solution

Verified by Experts

On moon, the acceleration due to gravity is `1//6^(th)` of its value on the surface of earth. So weight on the moon will also be `1//6^(th)` of the weight on the earth.s surface and does not become zero.
In an artificial satellite, apparent weight of the body `= m(g. - a)`, as a satellite is a freely falling body. Therefore a = g., so apparent weight of the body is zero and the person feels weightlessness.
