average speed, distance and time
speed = distance ÷ timespeed = distance⁄time
force, mass and acceleration
force = mass x acceleration
acceleration, change in velocity and time taken
acceleration = change in velocity ÷ time taken
density, mass and volume
density = mass ÷ volume
work done, force and distance moved
work done = force x distance moved
energy transferred and work done
energy transferred = work done
kinetic energy, mass and speed
kinetic energy = 1/2 x mass x speed2
gravitational potential energy, mass, g and height
gravitational potential energy = mass x g x height
weight, mass and gravitational field strength
weight = mass x gravitational field strength
pressure, force and area
pressure = force ÷ area
charge, current and time
charge = current x time
voltage, current and resistance
voltage = current x resistance
wave speed, frequency and wave length
wave speed = frequency x wave length
refractive index, angle of incidence, angle or refraction
n = sin i ÷ sin r
refractive index and critical angle
n = 1 ÷ sin c
efficiency, useful energy output and total energy input
efficiency = useful energy output ÷ total energy input
pressure difference, depth, density and g
pressure difference = density x g x depth
