Density- mass ÷ volume= gǀcm³ · Speed- distance ÷ time= mǀs · Acceleration- (final speed – first speed) ÷ time taken= mǀs² · Moment of a force- force x perpendicular distance= Nm · Pressure- force ÷ area= Nǀm² · Work- force x distance= J · Power- work done ÷ time taken= W · Voltage- Current (I) x resistance (Ω)= V · kWh- number of kW x number of hours
