  1. Sample Conceptual Physics Test Questions From their powerpoint notes

  2. Assessment Questions • If a falling object gains 10 m/s each second it falls, its acceleration can be expressed as • 10 m/s/s. • 10 m/s2. • v = gt. • both A and B.

  3. Assessment Questions • If a falling object gains 10 m/s each second it falls, its acceleration can be expressed as • 10 m/s/s. • 10 m/s2. • v = gt. • both A and B. Answer: D

  4. Assessment Questions • A rock falls 180 m from a cliff into the ocean. How long is it in free fall? • 6 s • 10 s • 18 s • 180 s

  5. Assessment Questions • A rock falls 180 m from a cliff into the ocean. How long is it in free fall? • 6 s • 10 s • 18 s • 180 s Answer: A

  6. Assessment Questions • The slope of a speed-versus-time graph represents • distance traveled. • velocity. • acceleration. • air resistance.

  7. Assessment Questions • The slope of a speed-versus-time graph represents • distance traveled. • velocity. • acceleration. • air resistance. Answer: C

  8. 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.

  9. 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. Answer: B

  10. Assessment Questions • Speed and acceleration are actually • one and the same concept, but expressed differently. • rates of one another. • entirely different concepts. • expressions of distance traveled.

  11. Assessment Questions • Speed and acceleration are actually • one and the same concept, but expressed differently. • rates of one another. • entirely different concepts. • expressions of distance traveled. Answer: C

  12. Ch.6 Assessment Questions • Which of these expresses a vector quantity? • 10 kg • 10 kg to the north • 10 m/s • 10 m/s to the north

  13. Assessment Questions (6) • Which of these expresses a vector quantity? • 10 kg • 10 kg to the north • 10 m/s • 10 m/s to the north Answer: D

  14. Assessment Questions • An ultra-light aircraft traveling north at 40 km/h in a 30-km/h crosswind (at right angles) has a groundspeed of • 30 km/h. • 40 km/h. • 50 km/h. • 60 km/h.

  15. Assessment Questions • An ultra-light aircraft traveling north at 40 km/h in a 30-km/h crosswind (at right angles) has a groundspeed of • 30 km/h. • 40 km/h. • 50 km/h. • 60 km/h. Answer: C

  16. Assessment Questions • A ball launched into the air at 45° to the horizontal initially has • equal horizontal and vertical components. • components that do not change in flight. • components that affect each other throughout flight. • a greater component of velocity than the vertical component.

  17. Assessment Questions • A ball launched into the air at 45° to the horizontal initially has • equal horizontal and vertical components. • components that do not change in flight. • components that affect each other throughout flight. • a greater component of velocity than the vertical component. Answer: A

  18. Assessment Questions • When no air resistance acts on a fast-moving baseball, its acceleration is • downward, g. • due to a combination of constant horizontal motion and accelerated downward motion. • opposite to the force of gravity. • at right angles.

  19. Assessment Questions • When no air resistance acts on a fast-moving baseball, its acceleration is • downward, g. • due to a combination of constant horizontal motion and accelerated downward motion. • opposite to the force of gravity. • at right angles. Answer: A

  20. Assessment Questions • When no air resistance acts on a projectile, its horizontal acceleration is • g. • at right angles to g. • upward, g. • zero.

  21. Assessment Questions • When no air resistance acts on a projectile, its horizontal acceleration is • g. • at right angles to g. • upward, g. • zero. Answer: D

  22. Assessment Questions • Without air resistance, the time for a vertically tossed ball to return to where it was thrown is • 10 m/s for every second in the air. • the same as the time going upward. • less than the time going upward. • more than the time going upward.

  23. Assessment Questions • Without air resistance, the time for a vertically tossed ball to return to where it was thrown is • 10 m/s for every second in the air. • the same as the time going upward. • less than the time going upward. • more than the time going upward. Answer: B
