- Weightlessness: The weight of a body is the force with which it is attracted towards the center of the earth.
- When a body is stationary with respect to the earth, its weight equals gravity. This weight of the body is known as its static or true weight.
EXPLANATION:
Weightlessness in a Satellite:
- A satellite, which does not produce its own gravity moves around the earth in a circular orbit under the action of gravity.
- The acceleration of the satellite is
towards the center of the earth. - If a body of mass m placed on a surface inside a satellite moving around the earth. Then force on the body is
The gravitational pull of the earth is
The reaction by the surface = R
By Newton’s second law,
⇒ R = 0
- Thus the surface does not exert any force on the body and hence its apparent weight is zero.
- A body needs no support to stay at rest in the satellite and hence all positions are equally comfortable. Such a state is called weightlessness.
