Question

In the earth-moon system the moon orbits the earth. What is the "centripetal" force causing the moon to stay in orbit around the earth

Answer 1

The centripetal force is the gravitational force of attraction between the Earth and the Moon.

Also, the gravitational force of attraction between the Earth and the Sun is the centripetal force that causes the Earth to stay in orbit around the Sun.

Also, the gravitational force of attraction between a TV satellite, a weather satellite, or a GPS satellite and the Earth is the centripetal force that causes each satellite to stay in orbit around the Earth.
