A hammer and a feather are dropped from the same height by an astronaut on a planet without air. How will their falls compare?(1 point)

Responses

The feather will fall faster because it has less mass, allowing it to speed up more easily than the hammer.
The feather will fall faster because it has less mass, allowing it to speed up more easily than the hammer.

The hammer will fall faster because gravity is pulling it down with a greater force than it is pulling the feather.

The objects will fall at the same time because gravity will have the same affect on them.
The objects will fall at the same time because gravity will have the same affect on them.

The objects will fall at the same time because gravity is not acting on them, so they will be affected the same.

The correct response is:

The objects will fall at the same time because gravity will have the same effect on them.

In a vacuum (a planet without air), all objects fall at the same rate regardless of their mass. This is due to the fact that the acceleration due to gravity is constant and acts equally on all objects. Thus, both the hammer and the feather will hit the ground at the same time.
