Motion

For a couple of weeks now we have been talking about Kinematics in class. Kinematics is the study of the forces that cause motion. The picture below is I bodysurfing at Sandy’s. Since I am riding the wave, relative to the wave I am not moving. Relative to the sand however, the wave and I are both moving. Acceleration is change in velocity over change in time. My acceleration after riding the wave for 2 sec. would be whatever velocity I am traveling at 2 sec. minus 0m/s (I wasn’t moving before I started on the wave), divided by 2 sec. minus 0 sec. Velocity is measured in m/s².
