Presentation Transcript

1. Gravity is continuously applied to an object, causing it to accelerate. After a period of time, however, the object stops accelerating. What conclusion can be drawn?

  • a. The mass of the object has increased.

  • b. Gravity on the object has increased.

  • c. The object reached terminal velocity.

  • d. The momentum of the object has reached a maximum.


2. Of the following, the greatest gravitational force would occur between

  • a. a marble and a baseball 5 meters apart.

  • b. a loaded freighter on the high seas and Earth.

  • c. the moon and an astronaut standing on the moon.

  • d. the moon and Earth.




  • 5. In the absence of air resistance, how would the acceleration of a 1.5 kg book and the acceleration of a 15 kg rock differ if the objects were dropped from the same height?

  • a. The book would accelerate twice as fast as the rock.

  • b. The rock would accelerate twice as fast as the book.

  • c. The book would accelerate ten times as fast as the rock.

  • d. They would not differ; they would be the same


6. What happens immediately after a sky diver opens her parachute?

  • a. Air resistance greatly increases.

  • b. The sky diver is in free fall.

  • c. The sky diver’s speed greatly increases.

  • d. The force of gravity greatly increases.








  • 13. Which statement about weight is incorrect? it is

  • a. An object weighs more on the moon than it weighs on Earth.

  • b. A change in an object’s location can change the object’s weight.

  • c. An object’s weight is directly proportional to its mass.

  • d. The weight of an object depends on gravity.




  • 16. Weight is best described as object, the velocity

  • a. an object’s resistance to acceleration.

  • b. what causes an object to fall.

  • c. the downward force exerted on an object due to gravity.

  • d. a force solely dependent on an object’s mass.



  • 18. Which of the following is true? acceleration?

  • a. Weight and mass are proportional but not equal.

  • b. Weight is gravitational force an object experiences due to its mass.

  • c. The weight of an object on Earth is greater than the weight of the same object on the moon, but the object’s mass stays the same.

  • d. All of the above




  • 21. When completing the Orbital Motion Lab, you found that path around another object, the object is said to be in

  • a. Objects with larger orbits travel at a faster speed than objects with smaller orbits.

  • b. Objects with larger orbits travel at a slower speed than objects with smaller orbits.

  • c. Objects with larger orbits travel the same speed as objects with smaller orbits.

  • d. None of the above.
