Unit 7 Test Review Part 1 (S8P5a, S8P5b & S8P5c)

• The force that pulls objects apart

• The attraction between two masses

• The force that acts only on Earth

• The force of friction between two objects

• The temperature of the objects

Which of the following summarizes how distance affects gravitational attraction?

• Greater distance leads to stronger attraction

• Closer objects experience weaker attraction

• Attraction decreases as distance increases

• Distance has no effect on attraction

After collecting data on gravitational force and distance, you find that as distance increases, the force decreases. What can you conclude?

• Distance does not affect gravitational force

• Gravitational force is constant regardless of distance

• There is an inverse relationship between distance and gravitational force

• Gravitational force only depends on mass

If a person weighs 60 kg on Earth, how would their weight change on a planet with higher gravity?

• It would increase.

• It would decrease.

• It would stay the same.

Answer explanation

Remember, mass is constant. I never changes with changes in gravity, but weight depends on gravity so if the force of gravity increase, weigh will increase.

What happens to the gravitational force between two objects as the distance between them increases?

• It increases.

• It decreases.

• It remains constant.

• It becomes unpredictable.

If the mass of one object is increased while keeping the distance constant, the gravitational force will:

• Decrease

• Remain the same

• Increase

• Become zero
