Newton’s First Law of Motion An object at rest will remain at rest and an object in motion will continue moving at a constant velocity unless acted upon by an unbalanced force. Things are LAZY…they keep doing what they’re already doing unless an UNBALANCED force causes a change! The La...

Now that we know Newtons Laws of Motion, how do we apply them? How can they let us predict the motion of an object if we know all the forces acting upon it? How can they let us predict the forces on an object if we know its motion? FORCE = MASS times ACCELERATION or Kobes car...
