Question
What would happen to the Moon if the gravity of the Earth was lost someday?
- It would fly away in a tangential direction.
- It would only rotate in its position and not revolve anymore
- It would burst
- It would hit the Earth’s surface
Hint:
The moon is always in motion and will continue to be so as per Newton's First Law of Motion
The correct answer is: It would fly away in a tangential direction.
The moon keeps a steady horizontal pace which keeps it from crashing into the Earth. If the Earth's gravity were to be removed, the moon, obeying Newton's First Law of Motion, will continue this horizontal motion with the same speed, and hence, will fly away from the Earth in a tangential direction.
