Big idea: forces and motion

Force is a useful idea because it is the key to explaining changes in the motion of an object or in its shape.  The motion of an object can be explained or predicted if you know the sizes and directions of all the forces that act on it.  Understanding forces help us to predict and control the physical world around us.
