Law of Gravity

As distance between two objects increase the pull of gravity 

• Increases

• Decreases

• Stays the same

A person would weigh less on on the Moon than on the Earth because . . .

• Moon has more mass, and therefore more gravity

• Moon has less mass, and therefore more gravity

• Moon has more mass, and therefore less gravity

• Moon has less mass and therefore less gravity

The strength of the force of gravity depends on

• The weight of the objects and their speeds

• The distance of the objects and their speeds

• The masses of the objects and the distance between them

• Mass of the objects and their speeds

The gravitational attraction between two objects would increase if both masses are –

• increased, and the distance between them is increased.

• increased, and the distance between them is decreased.

• decreased, and the distance between them is decreased.

• decreased, and the distance between them is increased.

If the distance between Mercury and the Sun were increased, what could be done to maintain the same gravitational force of attraction between Mercury and the Sun?

• Decrease the masses of Mercury and the Sun.

• Decrease Mercury’s speed of orbit around the Sun.

• Increase the masses of Mercury and the Sun.

• Increase Mercury’s speed of orbit around the Sun.
