Question 1
1 / -0

Weightlessness experienced while orbiting the earth in space-ship, is the result of

A
Inertia

B
Acceleration

C
Zero gravity

D
Free fall towards earth

Solution

A body is said to be weightless only if the force of gravity is acting on it and nothing is opposing it. In a spaceship around the earth, every part and parcel of the spaceship has an acceleration towards the center of the earth which is exactly the value of earth’s acceleration due to gravity at that position. Thus in the spaceship everything inside it is in a state of free fall.
