Question

Astronaut David Scott drops a hammer and a feather simultaneously. They both hit the Moon's surface at the same time. If the same experiment was conducted on Earth, the hammer would hit the ground first...

because it experiences a greater acceleration of gravity than the feather.
because it experiences much less air resistance force than the feather and thus reaches a larger terminal velocity.
because its air resistance force relative to its weight is much smaller, compared to the feather.
because its cross sectional area is smaller than that of the feather.
because g on Earth is larger than on the Moon.

Expert Solution

Step 1: Discuss the condition on Moon

On moon, there is no air. So, air resistance on both objects are zero.

Hence, they both fall in same time.
