Motion of the Center of Mass
In this video Paul Andersen explains how linear motion of an object can be measured using the center of mass. Internal forces within the object can be ignored since they exist in action reaction pairs. A simple way to determine the...

Forces
Forces are pushes or pulls on an object. Forces can be determined by measuring the motion of an object. If an object accelerates then a force is present.

Bozeman Science: Position vs Time Graph Part 2
Mr. Andersen shows you how to read a position vs. time graph to determine the velocity of an object. Objects that are accelerating are covered in this video. He also introduces the tangent line (or the magic pen). [13:01]

Bozeman Science: Newton's Second Law
In the following video Paul Andersen explains how Newton's Second Law applies when a net force acts on a body. The net force vector and the acceleration vector will act in the same direction. If an object acts on another object in a...
