Is it true that the moon falls?

• No, it could have fallen by now.

• No, there is no good explanation as to why

• Yes, the moon is falling around the earth due to its tangential velocity.

• Yes, the moon is falling straight down.

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

• increase because gravitational force increases

• decrease because gravitational force decreases

• decrease because gravitational force increases

• nothing, mass is not affected by gravitational force

The radius r (the distance between the masses), is found by measuring

• From the nearest surface of one object to the other's surface

• From the center of one mass to the center of the other's center

• From the farthest surface of one object to the other's surface

The law of universal gravitation is credited to whom?

• Einstein

• Galileo

• Darwin

• Newton

Which configuration will result in the greatest gravitational force?

• small masses far apart

• large masses far apart

• small masses close together

• large masses close together

What is the proper setup of the gravitational force formula?

• F_g= Gm²/r

• F=ma

• F_g= Gr²/(m₁+m₂)
