Pass Check: Motion-Time Graphs
Distance-time and velocity-time graphs: gradients give speed and acceleration.
Distance-time graph
A graph showing distance travelled against time; gradient gives speed.
Velocity-time graph
A graph showing velocity against time; gradient gives acceleration.
Acceleration
The rate at which velocity changes over time.
Area under a velocity-time graph
Represents the total distance travelled.
