Newton's Laws

Isaac Newton's theory of mechanics, describing the motions of objects, and the law of gravitation. Newton's three laws are:

1. Newton's First Law: The law of motion which states that an object in a state of uniform motion will remain in that state unless acted upon by an external force.
2. Newton's Second Law: The law of motion which states that the net applied force on an object produces an acceleration in proportion to the mass, F = ma.
3. Newtons' Third Law: The law of motion which states that if A exerts a force on B, then B will exert an equal and oppositely directed force on A. For every action, there is an equal and opposite reaction.
