28 nov 1686 anni - Newton's Laws of Motion

Descrizione:

Newton described 3 different laws of motion. The first law states that a object will stay in its current state (moving or staying still) unless the object is compelled to move from an external force and the object will stay at the same velocity, but if the object interacts with the external force the velocity of the object will change. The second law states how the external force affect the object, the law states, "force to be equal to change in momentum (mass times velocity) per change in time." So that means that force is equal to mass times acceleration. Finally the last law explains that for every action there is an equal and opposite reaction.
