Newtons Laws in physics

  Newton's 1st Law: the Law of Inertia An object at rest tends to stay at rest, and an object in motion tends to stay in motion.  or,  An object at rest will stay at rest and an object in motion will stay in motion unless acted upon by an unbalanced force.  Newton's 2nd Law: the Law of Proportionality  The acceleration of an object is directly proportional to the net force and inversely proportional to its mass. Definitions: Force: a push or a pull on an object Mass: a measure of the amount of material in an object; a quantitative measure of inertia  Acceleration: the rate of change of velocity with time  Newton's 3rd Law:the Law of Interaction  For every action there is an equal and opposite reaction. ...
