Position vs. time graphs, One-dimensional motion, Physics

David explains how to read a position vs. time graph. He then explains how to use the graph to determine the following quantities: displacement, distance, average velocity, average speed, instantaneous velocity, and instantaneous speed.


Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.
