A force is the action of one body on another. This force can come from an actual physical contact between bodies or through a body force due to a gravitational or magnetic field. An idealize forces acts in a well-defined direction and at a single location. In actuality forces are usually applied over a finite area. The units of force are N (Newtons) or lbf (pound force).





Acceleration is the time rate of change of velocity (a = dv/dt)


Think about how you know that you are accelerating?
