If Kiera stands on the Moon holding a hammer, and she lets go of the hammer, what happens to the hammer, and why does this happen? Provide a very short response.
The hammer falls to the Moon's surface. This happens because the Moon, like Earth, has its own gravitational pull that attracts objects towards it, although the Moon's gravity is weaker than Earth's. When Kiera releases the hammer, there are no other significant forces acting on it, so gravity takes over and pulls it downward towards the Moon.
