What are distance-time graphs?Show answer
On a distance-time graph, the gradient is the speed:
What are speed-time graphs?Show answer
On a speed-time graph, the gradient is the acceleration:
What is keeping units consistent?Show answer
Convert all times and distances to consistent units before reading gradients or areas, usually seconds and metres so that speed is in metres per second. Mixing minutes and seconds is a frequent source of error.
