1 janv. 1687 - Sir Isaac Newton - The four Newton's laws

Description:

1) An object at a state of rest will remain so, and an object that moves at a fixed velocity if no force is acting on it.

2) A force that is applied to an object changes the rate of change in the momentum's direction on the force's direction.

3) If one object applies force to a second object, then the second object applies the same force to the first object, only in the opposite direction.

4) The gravitational force is directly proportional to the product of the masses of the bodies and inversely proportional to the square of the distance between them.
