Distance-time graphs for accelerating objects - Higher

If the speed of an object changes, it will be accelerating or decelerating.

This can be shown as a curved line on a distance-time graph.

A graph to show distance travelled by time. A shows acceleration, B shows constant speed, C shows deceleration, and A shows stationary position. Three dotted lines separate each section.

The table shows what each section of the graph represents:
