Understanding Gravity Competition

What is gravity?

• A type of electromagnetic force

• The force that attracts a body towards the center of the earth, or towards any other physical body having mass

• A force that repels objects away from each other

• The force responsible for the Earth's rotation around the Sun

Which of the following best describes the effect of gravity on light objects compared to heavy objects? (Hint: we saw this when we watched the video of the feather and bowling ball being dropped in an airless chamber)

• Gravity does not affect heavy objects

• Gravity affects light and heavy objects equally

• Gravity does not affect light objects

What happens to the gravitational force between two objects if the mass of one object increases?

• The gravitational force decreases

• The gravitational force remains the same

• The gravitational force increases

• The gravitational force becomes zero

If the distance between two objects doubles, what happens to the gravitational force between them?

• The gravitational pull increases

• The gravitational pull stays the same

• The gravitational pull decreases

What is the relationship between mass and weight?

• Weight is the amount of matter in an object, while mass is the force of gravity on that object

• Mass and weight are the same thing

• Mass is the amount of matter in an object, while weight is the force of gravity on that object

• Mass increases with height, while weight decreases

Which unit is used to measure weight?

• Kilogram (kg)

• Newton (N)

• Meter (m)

• Gram (g)

What would happen to your weight if you went to the moon?

• It would increase

• It would decrease

• It would stay the same

• You would become weightless

Why can astronauts jump higher on the moon than on Earth?

• Because there is no gravity on the moon

• Because the gravitational pull on the moon is much less than Earth

• Because the gravitational pull on the moon is much greater than on Earth

• Because their mass decreases in space

How does the gravitational force between two objects change if the mass of both objects is increased?

• It remains the same

• It increases

• It decreases
