I. The ball has constant acceleration as it moves upward.
II. The ball has constant acceleration at the top of its path.
III. The ball has constant acceleration as it moves downward.

If a dropped object on Earth was equipped with a speedometer, its speed reading would increase each second by
about 5 m/s.
about 10 m/s.
about 15 m/s.
a rate that depends on its initial speed.
On Earth, the reason a feather falls slower than a bowling ball is due to
air resistance
the feather being lighter than the bowling ball
the feather having less mass
A baseball is thrown up into the air. What direction is the acceleration due to gravity on the ball the instant after it leaves the person's hand?
upward
downward
What kind of motion does this distance-time graph represent?
Constant Speed

Not moving
Do free falling objects move at constant velocity or do they accelerate?
Falling objects accelerate at 10 m/s2
Falling object move at constant velocity
Falling objects accelerate at 100 m/s2
It depends on the mass: heavy objects accelerate, light objects do not
