### Gravitational Review

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.

• 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

• 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.
