Write four phenomena that were successfully explained using the universal law of gravitation.

1. The universal law of gravitation states that every object in the universe attracts the other objects with a force whose magnitude is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
2. The motion of the planets around the sun and the stability of the solar system are explained by the law of gravitation.
3. The motion of the moon around the earth is due to the phenomenon of gravitation.
4. The force that binds us to the earth is none other than the gravitational force.
5. The same force holds the atmosphere around the earth.
