True
False
Acceleration due to gravity on or near the surface of planet earth is 9.8 m/s/s.
True
False
Objects fall slower than 9.8 m/s/s primarily because of air resistance.
True
False
Newton’s Law of Universal Gravitation states that the force of gravity between two objects depends on the mass of the objects and how fast they are moving.
True
False
When a falling object reaches terminal velocity, the forces acting on the object are balanced.

Which statement best describes the relationship between the weight and mass of an object?
If mass increases, weight will decrease.
If mass increases, weight will increase.
Doubling mass reduces weight by half.

What happens to the mass and weight of an object that is launched into space, where the pull of gravity is less?
The mass decreases while the weight stays constant.
The mass stays constant while the weight increases.
The mass increases while the weight decreases.
The mass stays constant while the weight decreases.
Jennifer is explaining the difference between weight and mass to her little sister. In comparing the two, which of the following could Jennifer use to correctly describe the weight of an object?
