Question
An airplane is flying in the sky. Is the Earth’s gravity acting on it?
- No
- Yes
- Sometimes
- None of the above
Hint:
The Earth’s gravity is a force that pulls objects towards its center. Any object that lies on the Earth or near it is pulled towards itself because of gravity.
The correct answer is: Yes
The Earth's gravity acts on an airplane flying in the sky. Had it not been for the Earth's gravity, the plane would fly out in the outer space.
Hence, Yes, the Earth's gravity acts on an airplane flying in the sky.

A ball is thrown up in the air. Initially, the ball moves upwards, i.e., against the direction of the gravitational pull of the Earth and then starts moving towards the Earth. Does it mean that the ball was not subjected to the Earth’s gravity when it was moving upwards?
