Gravity Quiz

The gravitational force between two objects is 100 N. If the mass of each object is doubled, what is the gravitational force between the objects at the same distance?

400 N

Which change will always result in an increase in the gravitational force between two objects?

increasing the masses of the objects and decreasing the distance between the objects

The force that one massive object exerts to attract another object is called _______.

Gravity

Which describes an object in projectile motion? Check all that apply.

Gravity acts to pull the object down. The object's inertia carries it forward. The path of the object is curved.

Hector drew the diagram below to illustrate projectile motion. How should Hector correct his diagram?

He should make the arrow for "Path" curve downward.

A ball is thrown forward at 5 m/s. How would the path of the ball differ on Earth than on the moon?

The ball would curve down more sharply on Earth than on the moon.

Which statement best compares the accelerations of two objects in free fall?

The objects have the same acceleration.

Which factors affect the gravitational force between two objects?

mass and distance

When does a skydiver achieve terminal velocity?

when gravity equals air resistance

A spacecraft is launched from Earth toward the moon. Where will the spacecraft be when the gravitational forces acting on it are equal?

closer to the moon than to Earth because Earth has greater mass than the moon
