Question  Answer 
Power Of A Lens In Dioptres  P=1/f Power (d) = 1/focal length (m) 
Magnification Of A Lens  m=v/u m = Image Height / Object Height 
Resistance  V = I x R OR R = V/I = Resistance = Voltage/Current 
Conductance  G = I/V = Conductance = Current/Voltage OR G = 1/R = Conductance = 1/Resistance 
Power  P = VI = Power = Voltage x Current OR V = P/I = Voltage = Power/Current 
Acceleration  a = (Final Velocity  Initial Velocity) / Time v and u is in meters per second t is in seconds 
Average Velocity  
Displacment  Displacement = Average Velocity x time (s) OR 
Newtons 2nd Law  When mass is constant: F = ma Where F is the resultant force When mass isn't constant: F = ΔP/Δt Where p is momentum and t is time 
Kinetic Energy  
Gravitational Potential Energy  GPE = mgh GPE = Mass x Gravitaional Field Strength x Height 
Energy of a Photon  E = hc/λ OR energy = (Plancks constant X speed of light) / wavelength in meters
