Unit 2 Segment B: Speed and Velocity We head to the Porsche test track to learn about the difference between speed ... and we investigate how to find information from a position versus time graph.

Speed-time graphs show how the speed of a moving object changes with time. Key facts. Gradient of speed-time graph = rate of change of speed (m/s 2). Area under speed-time graph = distance ...

To access more detailed trip information, tap on the speed graph. You'll find total distance, moving time, stopped time, total time, moving average, and overall average.
