Lesson details
Lesson outcome
I can calculate time intervals and acceleration of sections of a speed/time graph.
Show transcript
In a speed-time graph, a horizontal line means the speed did not change during that time.
A slanted line means the speed is changing.
You find this by considering the change in speed with respect to the change in time.
This is how you find the gradient of the line, which is also the acceleration.
A negative gradient means there is deceleration.
