On Earth, why is it that a hammer and a feather will fall at different speeds?

• more air resistance acting on feather

• more air resistance on hammer.

• more gravity acting on the feather.

• more gravity acting on the hammer.

on the moon, if a feather and a hammer are dropped from the same height, what happens?

• they land at the same moment

• the hammer lands first

• the feather lands first

• they float since there is no gravity on the moon
