A shoe and a shirt are released from the same height. They take different amounts of time to fall to the ground. How can this be explained?(1 point)
Responses
The weight is greater on the shoe than on the shirt, but there is equal air resistance on the objects.
The weight is greater on the shoe than on the shirt, but there is equal air resistance on the objects.
The difference in weight doesn't affect the time, but they are affected differently by air resistance.

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