What is gravitational force?

• a force that attracts any object
• a force that pushes any object
• a force that shrinks any object
• a force that enlarges anyobject

A moon is located at 1 unit out from the planet it orbits. If that moon was orbiting at 2 units out from the planet, how much would the gravitational force on the moon be compared to its distance at 1 unit?

• twice as much

• 4 times as much

At what point is the force of gravity on an object greatest

• At the center of the earth (Core of the earth)

• At twice the distance from the surface of the earth

• At the surface of the earth

• The force of gravity ios the same irrespective of distance from the center of the earth

Is it true that the moon falls?

• No, it could have fallen by now.

• No, there is no good explanation as to why

• Yes, the moon is falling around the earth due to its tangential velocity.

• Yes, the moon is falling straight down.

The larger the mass of an object...

• The smaller the force of gravity.

• The larger the force of gravity.

• Mass has no effect on the amount of gravity an object experiences.

As the distance between objects increases...

• The smaller the force of gravity.

• The larger the force of gravity.

• Mass has no effect on the amount of gravity an object experiences.
