Motion
Speed, velocity, acceleration and describing movement with graphs.
01Speed and VelocityCalculating speed from distance and time, and seeing how velocity adds direction.Read lesson →02Distance–Time GraphsReading journeys from graphs and finding speed from the gradient.Read lesson →03What Is AccelerationWorking out how quickly velocity changes using a = (v − u) ÷ t.Read lesson →04Velocity–Time GraphsFinding acceleration from the gradient and distance from the area under the graph.Read lesson →
