Weight (w): w = mg (where m = mass, g = gravitational field strength)
Mass (m): m = w/g (from weight formula)
Gravitational field strength (g): g = w/m (from weight formula)

Voltage (V): V = IR (from resistance formula)
Power (P): P = work done/time taken
Power (P): P = IV (where I = current, V = voltage)
Efficiency: efficiency = (useful output/total input) × 100%
Refractive index (n): n = (speed of light in air)/(speed of light in medium)
Work done: work done = force × distance in direction of force
Potential energy (Ep): Ep = mgh (where m = mass, g = gravitational field strength, h = height)
Height (h): h = Ep/mg (from potential energy formula)
Kinetic energy (KE): KE = ½mv² (where m = mass, v = velocity)
Hooke's Law Force (F): F = kx (where k = spring constant, x = extension)
Spring constant (k): k = F/x (from Hooke's Law)
