Friction always
acts in the direction opposite of motion
acts in the same direction as the motion of an object
helps an object move
causes an object to cool

In the absence of air resistance (no air, a vacuum) how would the movement of a feather differ from that of a hammer when dropped from rest?
No difference they was be the same
The hammer would fall much faster than the feather
the hammer would fall with an acceleration of 9.8 m/s2 while the feather would fall but with a slower acceleration.
The feather would fall faster than the hammer
