Motion: speed, velocity and acceleration

Describe how things move with numbers: speed and velocity, acceleration, and the equations of motion for constant acceleration.

Level: Upper secondary and first-year university

  1. 1Speed and velocityWork out average speed from a distance and a time. Tell distance from displacement, and speed from velocity. Convert between km/h and m/s.Free to read · 4 practice questions
  2. 2AccelerationWork out acceleration from a change in velocity and a time. Read acceleration from a velocity–time graph.Members · 4 practice questions
  3. 3The equations of motionChoose the right equation of motion for a problem. Solve free-fall problems using g = 9.8 m/s².Members · 4 practice questions
