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 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 hammer will fall faster because gravity is pulling it down with a greater force than it is pulling the feather. 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 is not acting on them, so they will be affected the same. 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.

Answer 1

The correct response is: The objects will fall at the same time because gravity will have the same effect on them.

In a vacuum or a planet without air resistance, all objects fall at the same rate regardless of their mass. This is a fundamental principle of physics, as demonstrated by Galileo's famous experiments and later confirmed by experiments conducted on the Moon by astronauts. Therefore, the hammer and the feather would hit the ground simultaneously if dropped from the same height in an environment without air.
