Distance, speed and velocity
Distance, displacement, speed, velocity and average speed.
Acceleration and slowing down
Equal changes in velocity, units and non-uniform acceleration.
Distance-time graphs
Read speed from the gradient for motion in one direction.
Speed-time graphs
Read acceleration from gradient and distance from area.
