Expert Answer
situations when the weight of the body is zero.
1)Weightlessness is experienced by astronauts in the orbits around the earth because the gravitational force of attraction of the earth is cancelled by the force that appears because of the circular motion of the astronaut around the earth.
2)Weightlessness is also observed during free fall that is if a lift allowed to fall; the people inside the lift will experience no weight.
