Motion, graphs and Newton’s laws

By the end you’ll be able to

• Distinguish distance from displacement and speed from velocity, use s = vt, and recall typical speeds for walking, running, cycling and sound
• Draw and interpret distance–time and velocity–time graphs: gradients for speed and acceleration, (HT) tangents for instantaneous speed, and area under a velocity–time graph for distance travelled
• Calculate acceleration (a = Δv/t), use v² − u² = 2as, recall g ≈ 9.8 m/s² and explain terminal velocity
