Can you explain each of these out loud, without looking? If not, re-read that lesson.
- Speed and Velocity: Calculating speed from distance and time, and seeing how velocity adds direction.
- Distance–Time Graphs: Reading journeys from graphs and finding speed from the gradient.
- What Is Acceleration: Working out how quickly velocity changes using a = (v − u) ÷ t.
- Velocity–Time Graphs: Finding acceleration from the gradient and distance from the area under the graph.
- Read each lesson's summary and re-do its practice questions from memory.
