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)

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 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 correct response is:

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

In a vacuum, where there is no air resistance, all objects fall at the same rate regardless of their mass. Both the hammer and feather will experience the same gravitational acceleration and thus will hit the ground at the same time when dropped from the same height.
