More Motion

Physics A and B went into more detail with the idea of graphing motion and looked at several examples of position/time graphs for motion with constant velocity and accelerated motion. Constant velocity will be represented by a straight line on a position/time graph and the slope will equal the value for the velocity. Pay attention to positive and negative slopes - that indicates the direction of motion. Accelerated motion is represented by a curve on a position/time graph. We could assess instantaneous velocity from this graph (or by using a speedometer), but we'll concern ourselves mathematically only with constant-velocity motion when confronted with a position/time graph. Tomorrow, we'll add acceleration to our list of descriptors of motion and look at how acceleration is presented in a velocity/time graph.

Introductory Physics and Honors Physics reviewed for tomorrow's exam and folks were reminded that I am available before school tomorrow for any last-minute assistance. Remember to bring with you any review work that I let you hold onto as a study tool so it can be handed in tomorrow. On Friday, Introductory Physics begins the journey through motion and Honors Physics continues their motion journey with a look at 2-dimensional motion.
