What are the gravity laws?

Answer 1

There's really only one gravity law:

F = G M1M2/R2This tells the strength and direction of the gravitational forces between two

objects that have masses M1 and M2 , and are separated by the distance R .

If you have enough geometry and calculus to work with, this one formula gives

you the weight, falling acceleration and falling speed of any object on any planet,

as well as the shapes and periods of orbits, how to put an artificial satellite into

orbit, and the best paths to take when launching a probe to any planet, asteroid,

comet or moon in the solar system.

Answer 2

The laws of gravity describe the force of attraction between objects with mass. The most well-known example is Newton's law of universal gravitation, which states that every mass attracts every other mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Additionally, Einstein's theory of general relativity provides a more comprehensive understanding of gravity as the curvature of spacetime by mass and energy.
