There is a difference between seeing motion and understanding it. Everyday we see objects moving at various velocities, accelerating, stopping and changing direction without really understanding the basic nature of motion. In order to more accurately describe motion we use mathematics and graphing techniques to represent motion in a tangible way. Our understanding of motion and the forces involved with motion, enable us to construct useful mechanical systems which make our life easier.
