Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If a feather and hammer are dropped on the Moon at the same time from the same height they will hit the Moon’s surface at virtually the same time.
A
TRUE
B
FALSE
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -However, when the experiment was done on the Moon, the feather and the hammer both hit the ground at the same time because, in the absence of air resistance, all objects do in fact accelerate towards the ground at the same rate. As the Moon has virtually no atmosphere, there is virtually no air resistance.

Detailed explanation-2: -The answer? Based on Scott’s experiment, on the moon, both hammer and feather reached the ground at the same time, proving Galileo’s 400-year-old theory that objects dropped from the same height reach the surface at the same time regardless of their weight.

Detailed explanation-3: -The Apollo 15 Hammer-Feather Drop At the end of the last Apollo 15 moon walk, Commander David Scott (pictured above) performed a live demonstration for the television cameras. He held out a geologic hammer and a feather and dropped them at the same time.

Detailed explanation-4: -While gravity treats all objects equally, air resistance does not. Significant air resistance acting on the light feather slows it down. There is much less air resistance acting on the heavy hammer, so it isn’t slowed as much, and hits the ground first.

Detailed explanation-5: -Hammer has more mass than the feather. The Moon has the same mass for both of the falls. thus, The acceleration of the feather only depends on the mass of the moon.
