Speed-time graphs show speed on the vertical ... A negative gradient shows the rate of 'slowing down' or deceleration. Velocity-time graphs show velocity on the vertical axis.

At the Porsche test track, we learn the difference between speed ... velocity. Different types of velocity are explored, and we investigate how to find information from a position versus time graph.

Surprisingly, not all textbooks agree on the definition of speed ... the definition of average velocity. When the object goes from position 1 to 2, it will take some time. I will call this ...

Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient. Key fact The gradient of speed-time and velocity-time graphs represent acceleration.
