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.

Why do planets orbit the Sun?

• The Sun is the only celestial object that has a gravitational pull.

• The Sun’s chemical composition makes it attract planets.

• Only celestial bodies that emit light, like the Sun, can be at the center of an orbit.

• The Sun is the most massive object in our solar system, so it exerts the greatest gravitational pull.

Gravity can be defined as the –

• force of attraction between two or more masses.

• friction created when two objects are in contact.

• energy given off by stars due to nuclear reactions.

• path an object follows as it moves through space.

Gravity attracts all objects towards one another.

• False
• True
• It depends

Any object with mass has gravity.

• True
• Sometimes
• False
• Never

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
