Newton's Law Of Universal Gravitation

What is Newton’s law of universal gravitation?The principle that expresses the force of gravitational attraction between two bodies as a function of their mass and their distance.

The value of gravity changes at difficult altitudes on Earth because if its closer to Earths center the gravity value will increase. If its further away from Earths center, it's gravity value will decrease, due to the gravitional pull.

The formula for Newtons law of universal gravitation is F = Gm1m2/d2. We use this when we're trying to find the unknown force between two weights.

The G in the equation stands for the gravitational constant and its value is 6.67*10-11 m3 kg-1 s-2
