Forces and motion

Speed, velocity and acceleration, the graphs that show them, the equations of motion, Newton's laws and stopping distances.

Lessons

  1. Speed, distance and velocityDistance against displacement, speed against velocity, s = vt and changing km/h into m/s. 20 min, free
  2. Distance-time graphsRead a distance-time graph, find a speed from its gradient and spot when something stops or speeds up. 20 min, free
  3. Acceleration and velocity-time graphsAcceleration as change in velocity per second, deceleration, and what the gradient and the area of a velocity-time graph give you. 25 min, with the Forces and acceleration simulation, Plus
  4. The equations of motionv² − u² = 2as for braking distances and falling objects, and the SUVAT solver for checking your working. 25 min, with the SUVAT Solver and the Projectile motion simulation, Plus
  5. Newton's lawsBalanced and unbalanced forces, F = ma, weight, inertial mass and third law pairs, with the practical that tests them. 25 min, with the Forces and acceleration simulation, Plus
  6. Stopping distancesThinking distance and braking distance, what changes each, reaction times from a ruler drop, and why braking distance goes with speed squared. 20 min, with the Newton's second law simulation, Plus
