| 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 |
| Slit Seperation |
