It is essential for students to know that the force of gravityis a pull between all objects in the universe. This force is influenced by the mass of the objects and the distance between them.
A more massive object has the greater pull on the less massive objects; the Sun being most massive object in the solar system has the greatest pull on objects, like planets, in the solar system.
The closer the distance between objects the greater the pull; the Moon has a greater effect on Earth’s tides than the Sun because it is closer to Earth.
These two factors of gravitational force have numerous applications on motions of celestial bodies, for example the gravitational pull between the Sun and the planets and between Earth and its Moon cause distinct motions between and among these bodies
