Question

An Astronaut on the Moon simultaneously drops a bird feather and a screw driver. The fact that two objects reach the surface at the same time can be explained by which of the following?

Answer 1

D. At the given location all objects fall with the same acceleration in the absence of air resistance

Explanation:

• The moon has its own gravity force like the Earth, hence the falling of the two objects with same speed is not related to gravity.
• As we know, there is no air on moon and hence there will be no air resistance.
• In the absence of the air resistance, the mass of any object would not matter and every object will fall with the same speed and force.
• This is the reason why a bird feather and a screw driver fall with the same speed on moon but not on Earth.
