In symbols the magnitude of the attractive force F is equal to G the gravitational constant a number the size of which depends on the system of units. Newtons first law of motion states that An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force Objects tend to keep on doing what theyre doing In fact it is the natural tendency of objects to resist changes in their state of motion.

Newtons universal law of gravitation formulated in his great work of mathematical physics the Principia published in 1687 was the first great work of force unification in physics. Newtons First Law of Motion states that an object in motion tends to stay in motion unless an external force acts upon it.

An object in rest or uniform motion in a straight will continue to be in rest or uniform motion unless and until acted upon by an external force. The formula that allows us to know what the thrust force is equal to is the following. Newtons law brought up the new concept where he said.
