Chapters

Press a chapter and the video starts at that topic.

1. 0:00Forces and EquilibriumResolving forces, tension, normal reaction and weight, three-force equilibrium, and friction including limiting equilibrium and the coefficient of friction.Quiz
2. 1:35:39KinematicsDisplacement, velocity and acceleration, the constant acceleration formulas, motion under gravity, displacement-time and velocity-time graphs, and using calculus when acceleration is not constant.Quiz
3. 3:21:42Newton's Second Law of MotionParticles on slopes and rough surfaces, connected particles with strings and pulleys, lifts, blocks on top of each other, and splitting motion into stages.Quiz
4. 4:32:47Work, Energy and PowerWork done by a force, kinetic and potential energy, conservation of energy, driving force and resistance, and power on level ground and on slopes.Quiz
5. 5:23:21MomentumConservation of momentum, collisions and particles that join together, and mixed questions that combine momentum with motion and energy.Quiz

How to use this video

1. Pick the topic you want to revise and start there, rather than watching from the top.
2. Pause before each worked question and try it yourself first.
3. Note any topic that still feels shaky, then practise it with topical past paper questions.
