Rearrange a formula

Final velocity v = u + at Velocity squared v² = u² + 2as Displacement s = ut + ½at² Average speed s = (u + v)t/2 Acceleration a = (v − u)/t

Rectangle area A = lw Perimeter P = 2(l + w) Triangle area A = ½bh Trapezium area A = (a + b)h/2 Circle area A = πr² Circumference C = 2πr Diameter C = πd Cuboid volume V = lwh Pythagoras c² = a² + b²

Straight line y = mx + c

Speed S = D/T Density D = M/V Pressure P = F/A

Force F = ma Ohm’s law V = IR Power P = IV Energy E = mc²

Letter twice x = (y + 5)/(y − 1) Two reciprocals 1/f = 1/u + 1/v
