2.4 Physics Motion Diagrams | General Physics

Chad provides comprehensive lesson on Physics Motion Diagrams. The lesson begins with Position vs Time Motion Diagrams in which an object's position is plotted on the y-axis and can be used to find displacement. Additionally, the slope of a Position vs Time graph is equal to instantaneous velocity. Chad provides a Position vs Time Graph example and demonstrates how to answer a series of practice questions for it.

Chad then moves on to Velocity vs Time Motion Diagrams in which an object's velocity is plotted on the y-axis. The slop of a Velocity vs Time graph is equal to acceleration, and the area under the curve is equal to displacement. Chad provides a Velocity vs Time graph example and demonstrates how to answer a series of practice questions for it.

Finally, Chad introduces Acceleration vs Time Motion Diagrams. Students will not likely be performing calculations with Acceleration vs Time graphs, but should recognize what such a graph would look like for three different situations: constant velocity (i.e. acceleration equal to zero), constant acceleration, and varying acceleration. Chad presents Acceleration vs Time graph examples for all three of these cases.
