05

Hooke’s law

Teacher-written GCSE Physics revision on Hooke’s law: F = ke up to the limit of proportionality, spring constant in N/m, force–extension graphs, and elastic versus inelastic deformation.

Open guide
06

Moments

Teacher-written GCSE Physics revision on moments: moment = force × perpendicular distance, clockwise and anticlockwise balance, centre of mass, and levers as force multipliers.

Open guide
07

Pressure

Teacher-written GCSE Physics revision on pressure: p = F/A in pascals, liquid pressure p = hρg, atmospheric pressure, and why sharp blades and wide tyres are the same equation.

Open guide
08

Speed and velocity

Teacher-written GCSE Physics revision on speed and velocity: average speed = distance/time, velocity as a vector, typical speeds, and distance–time graphs where gradient is speed.

Open guide
09

Acceleration

Teacher-written GCSE Physics revision on acceleration: a = Δv/t in m/s², velocity–time graphs where gradient is acceleration and area is distance, and v² − u² = 2as when time is missing.

10

Newton’s laws

Teacher-written GCSE Physics revision on Newton’s three laws as distinct ideas: first-law inertia and zero resultant, second-law F = ma, and third-law pairs on two different objects.

11

Stopping distance

Teacher-written GCSE Physics revision on stopping distance: thinking plus braking, reaction-time factors, how braking distance grows with speed squared, and work done by the brakes.

12

Momentum

Teacher-written GCSE Physics revision on momentum: p = mv, conservation in a closed system, F = Δp/t, and crumple zones — Higher-tier Combined and Triple content, so check your paper.

Force and acceleration required practical

Plan the GCSE Physics force–acceleration investigation: trolley on a ramp or linear air track, F = ma setup, varying mass while controlling force, measuring acceleration, graph and friction controls.
