Physics Formulae

speed = distance

time

force = mass x acceleration

acceleration = change in velocity

time taken

density = mass

volume

work done = force x distance moved with force

energy transferred = work done

kinetic energy = ½ x mass x speed²

gravitational potential energy = mass x gravity x height

weight = mass x gravity

pressure = force

area

moment = force x distance from pivot

charge = current x time

voltage = current x resistance

electrical power = voltage x current

wave speed = frequency x wavelength

primary input voltage = primary turns

secondary input voltage secondary turns

n = sin i

sin r

sin c = 1

n

pressure difference = height x density x gravity
