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
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
wave speed, frequency and wave length
wave speed = frequency x wave length
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
