Answer 1

*give me the options*

Newton's law of gravity states that the Earth exerts a constant force on free bodies and that this force is directly proportional to mass. Gravity exists in different ways on all the planets in the solar system.

Gravity is one of the four fundamental forces that exist in nature. The other fundamental quantities are the electromagnetic interaction force, the weak force and the strong force. In a simple way, gravity is the greatness responsible for defining the weight of a body, vertical and downward force that keeps us united to the planet. Any object that moves in free fall is under the influence of the acceleration of gravity, which on Earth is equivalent to approximately 9.8 m / s2.

The value of gravity depends on the mass and size of each planet, natural satellite, star, etc.
