1.3 Test Review (Forces)

Which of the following statements best describes how gravitational force is affected by mass or distance?

• As the mass of the two objects increase, the gravitational force between the two objects

  increases.

• As the mass of the two objects increase, the gravitational force between the two objects

  decreases.

• As the distance between two objects increases, the gravitational force between the two objects increases.

• As the distance between two objects decreases, the gravitational force between the two objects decreases.

Joey was standing under an orange tree and noticed several oranges on the ground. Which force acts on the orange while on the ground?

• friction

• normal

• applied

• magnetic

4. What statement accurately compares the Earth's and the Moon's gravitational force?

• The Earth has a smaller gravitational force than the Moon, because it has more mass than the Moon.

• The Earth will have a larger gravitational force than the Moon, because it has more mass than the Moon.

• The Earth will have a larger gravitational force than the Moon, because it is closer to the

  Sun than the Moon is.

• The Earth will have a smaller gravitational force than the Moon, because it is farther from the Sun than the Moon is.

Destiny moved a blown up balloon back and forth across a wool cloth which caused the balloon to become charged with static electricity. Which of the following best describes the present in this scenario?

• The interaction between the wool cloth and the balloon, as well as the charged balloon

  are examples of contact forces.

• The interaction between the wool cloth and the balloon, as well as the charged balloon

  are examples of non-contact forces.

• The interaction between the wool cloth and the balloon is an example of a contact force,

  while the charged balloon is an example of a non-contact force.

• The interaction between the wool cloth and the balloon is an example of a non-contact

  force, while the charged balloon is an example of a contact force.

• Air resistance and gravity are both contact forces.

• Air resistance and gravity are both non-contact forces.

• Air resistance is a non-contact force, and gravity is a contact force.

• Air resistance is a contact force, and gravity is a non-contact force.

How does gravitational force relate to distance?

• As objects move away from each other, the gravitational force increases.

• As objects move away from each other, the gravitational force decreases

• As distance remains the same between objects, the gravitational force increases.

• As distance decreases between objects, the gravitational force does not change.
