- 1density = mass / volumeρ = m/v
- 2pressure = force / areaP = F/A
- 3Pressure = density x gravity x heightP = pgh
- 4Boyles LawP1 V1 = P2 V2
- 5The Pressure LawP1/T1 = P2/T2
- 6Voltage = Current x ResistanceV = IR
- 7Charge = Current x timeQ = IT
- 8Power = Current x VoltageP = IV
- 9Energy = Current x time x VoltageE = ItV
- 10wave speed = frequency x wavelengthv = fλ
- 11frequency = 1/Time Periodf = 1/T
- 12Efficiency =useful energy output / total energy input
- 13refractive index = sine (angle of incidence) / sine (angle of refraction)n = sin(i) / sin(r)
- 14refractive index = 1 / sine (critical angle)n = 1 / sin (c)
- 15Work Done = Force x displacementW = Fd
- 16Gravitational Potential Energy = mass x gravity x heightGPE = mgh
- 17Kinetic Energy = 1/2 (mass x speed^2)KE = 1/2(mv^2)
- 18Power = Work Done / timeP = W/t
- 19GPE gained = KE lostGPE lost = KE gained
- 20average speed = distance moved / time takens = d/t
- 21acceleration = (change in velocity) / time takena = (v - u)/t
- 22Force = mass x gravityF = mg
- 23Weight = mass x gravityW = mg
- 24Moment =Force x perpendicular distance from the pivot
