weight Mass x gravitational field strength
force (Newton 2nd Law) Mass x acceleration
Stopping distance Braking distance + thinking distance
force acting Change in momentum/time taken for change
momentum Mass x velocity
moment Force x distance perpendicular between line of action and pivot
Total anticlockwise moments Total clockwise moments
force (Hooke's Law) Spring constant x extension
Circular motion Velocity2/radius
Orbital speed 2(pie)r/time
Electrical power Current x voltage
Energy transferred Current x voltage x time
voltage Current x resistance
charge Current x time
speed Frequency x wavelength
