Position vs. Time

In this picture, we see a local skater doing an air out of a bowl.  Whats appealing to the eye has a
greater meaning.  With a "Physics Mentality" we see position vs time.  As the skater drops into the bowl, he accelerates down the ramp to generate speed.  As time goes on, he maintains this speed in order to air off the other side of the ramp.  Displacement is also a factor in this case.  If the skater decides not to do an air, he would turn around and go up the initial ramp he went down.  When the skater returns to his starting point, he displaces the area he covered going down the ramp.
