Motion is one part of what physicists call mechanics. Acceleration is a twist on the idea of velocity. There are two main ideas when you study mechanics. There are also more complex movements when an object's direction is changing. In order to really understand motion, you have to think about forces, acceleration, energy, work, and mass.
