Read each question carefully and answer to the best of your ability. Show all work for calculations. Assume g = 9.8 m/s² downwards for all problems unless otherwise specified.
1. Which of the following statements best describes an object in free fall?
It is moving upwards at a constant velocity.
It is accelerating due to gravity only, with no air resistance.
It has reached terminal velocity.
It is always falling downwards.
2. An object is dropped from a cliff. Ignoring air resistance, what is its speed after 3 seconds?
9.8 m/s
19.6 m/s
29.4 m/s
39.2 m/s
3. The constant acceleration due to gravity near the Earth's surface is approximately m/s².
4. When an object is thrown upwards, its velocity at the peak of its trajectory is m/s.
5. is the force that opposes the motion of an object through the air.
6. A ball is thrown vertically upward with an initial velocity of 20 m/s. How high does it go?
7. Explain the difference between mass and weight in the context of gravitational force.
8. In a vacuum, a feather and a hammer dropped from the same height will hit the ground simultaneously.
True
False
9. Air resistance always increases as the speed of a falling object increases.
True
False
10. A rock is thrown straight down from a bridge with an initial velocity of 15 m/s. If it hits the water 2.0 seconds later, what is the height of the bridge?
