There are three main laws which are called the Laws of Newton.
These laws make a whole and strong basis for the dynamic and mechanic laws whos'' principals started in the times of Archimedes in the 3rd century B.C.E.
the first law: the body will stay in it''s status- if it''s moving, it will keep on moving in a steady pace in a straight line ( of course only if there aren''t any exterier forces activated on it, or if there are forces who balancely effect it.) And of course if the body is static- it will stay so.
the second law: if there is a force activated on the body- it will give it an acceleration towards the force. therefore the size of the acceleration will be relative to the force effecting each body.
the third law: if a body activates force on another body, the other body will activate an equal and oppositely directed force on the first. this law is called "the law of action and reaction".
One of newton''s most important achievements is his ability to put the laws into effect in global phenomenons.
Newton proved that the astronomic observations of Johannes Kepler on planets can be explained by the gravitation law which also explains the moon''s movement around Earth.
