Objects on the surface of Earth experience a large downward force although the universal gravitational constant is very small. Which of the following best explains this phenomenon?
The universal gravitational constant only describes relationships between small objects in outer space.
Objects on Earth's surface exert a gravitational pull as strong as Earth's, regardless of the gravitational constant.
Earth's mass is large enough that its gravity remains strong even when multiplied by a small constant.
The universal gravitational constant increases in proportion with the mass of an object.
The force of gravity on the surface of the moon is about one-sixth the force of gravity on the surface of Earth. Which describes the relationship of mass and weight of an object on the moon compared to that on Earth?
Both mass and weight are greater on the moon.
Weight is the same, but mass is less on the moon.
Both mass and weight are less on the moon.
Mass is the same, but weight is less on the moon.
At a certain distance from the center of Earth, a satellite experiences a gravitational force, F. If the mass of the satellite was doubled and placed into the same orbit, what gravitational force would the satellite have acting on it?

F/4
4F
2F
