Gravity is a force between any two objects with mass. Why doesn't a person feel a gravitational force between him/herself and another person?

• A person doesn't exert a gravitational force.

• The two gravitational forces cancel each other out.

• The gravitational forces of people is so small it is overshadowed by that of Earth.

• There are so many people we are actually balanced by all the different gravitational forces.

The moon orbits our Earth. The opposite would never be true; the Earth would never orbit the moon. One reason is due to the force of gravity. The object ____________ has a greater gravitational force and that determines what satellites orbit around it

• with the greater mass

• containing mostly water

• with a thicker atmosphere

• with the greater diameter

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