Practice and tests
By the end you can
Calculate speed, velocity and acceleration, with units Read speed, acceleration and distance from motion graphs Use v² − u² = 2as for braking and falling Use F = ma and explain motion with Newton's laws Work out stopping distances and explain what changes them Plan and analyse the force, mass and acceleration practical Helps with: GCSE (AQA, Edexcel, OCR)
Next unit: Momentum Previous unit: Forces, work, elasticity, moments and pressure
