Notes on Newton`s Laws of Motion
... Newton’s Second Law of Motion • “The acceleration of an object is equal to the net force acting on it divided by the object’s mass” • Acceleration = net force/mass, or a = F/m • Mass is the amount of matter in an object and stays constant • Weight is the force of gravity on an object and can change ...
