If your weight is 504 N on Earth and 84 N on the moon, which of the following would be true on if you were able to travel to Neptune, a planet larger than Earth.

• Your weight would be the same.

• Your weight would be more due to a greater gravitational pull.

• Your weight would be less due to a greater gravitational pull.

• Your weight would be less due to a smaller gravitational pull.

• Your weight would be less due to a smaller gravitational pull.

A twelve pound bowling ball and a ten pound bowling ball are dropped at the same time from a second story science building. Which of the following is correct?

• Both bowling balls will hit the ground at the same time.

A person would weight less on the moon than on the Earth because:

• the moon has more mass and therefore more gravity.

• the moon has more mass and therefore less gravity.

• the moon has less mass and therefore more gravity

• the moon has less mass and therefore less gravity.

If the Earth's mass was cut in half, what would happen to your mass?

• increase because gravitational force increases.

• decrease because gravitational force increases.

• decrease because gravitational force decreases.

• nothing because mass is not affected by gravitational force.

Compare you weight and mass on Earth, if you were on the moon where gravity is 1.6 m/s/s:

• Your weight and mass would be less.

• Your weight would be less but your mass would remain the same.

• Your weight would remain the same, but your mass would be less.

• Your weight would increase, but your mass would stay the same.

Which of the following is not true?

• Gravity is a form of acceleration.

• An object with a negative acceleration would be slowing down.

• Mass has the property of inertia which is resistance to change in motion.

• Weight is a scalar quantity. Mass is a vector quantity.
