When will the forces of gravity between two objects be the GREATEST?

• when the masses of both objects are small and the objects are far apart

• when the masses of both objects are large and the objects are close together

• when the masses of both objects are small and the objects are close together

• when the masses of both objects are large and the objects are far apart

The Mars Rover Opportunity had a weight on Mars of about 750 pounds. Mars is a less massive planet than Earth. Predict what would have been its weight on Earth?

• More than 750 pounds (about 2,000 pounds)

• Less than 750 pounds (about 300 pounds)

• About 750 pounds

A person would weigh more on Jupiter than on the Earth because . . .

• Jupiter has more mass, and therefore more gravity

• Jupiter has less mass, and therefore more gravity

• Jupiter has more mass, and therefore less gravity

• Jupiter has less mass and therefore less gravity

Which model has greater gravitational attraction (if any)

• Model A
• Model B
• Both Model A and Model B (same gravity)

How does changing the distance between objects affect the force of gravity?

• Decreasing distance increases gravity

• Increasing distance increases gravity

• Mr. Deem knows, but he's not telling

• Distance does not affect gravity

Match the term: The tendency of an object to resist a change in its motion

• acceleration

• inertia

• mass

• frame of reference

Suppose that this person left go of the chain. As soon as he releases the chain the balls inertia would....

• make the ball immediately stop and fall straight to the ground.

• keep the ball moving in a circle around him.

• result in the ball flying off in a straight line away from the person.

• either a, b, or c -- depending on whether the person continues to push it
