The slope of a speed-versus-time graph represents distance traveled.
Assessment Questions The slope of a speed-versus-time graph represents distance traveled. velocity. acceleration. air resistance.
7
The slope of a speed-versus-time graph represents distance traveled.
Assessment Questions The slope of a speed-versus-time graph represents distance traveled. velocity. acceleration. air resistance. Answer: C
8
gravity doesn’t act in a vacuum.
Assessment Questions In a vacuum tube, a feather is seen to fall as fast as a coin. This is because gravity doesn’t act in a vacuum. air resistance doesn’t act in a vacuum. greater air resistance acts on the coin. gravity is greater in a vacuum.
