Acceleration = change in velocity/time taken |
De Broglie equation |
Wavelength of a particle (l = h/mv) |
Density |
Density (r) = mass/volume |
Double slit interference |
Wavelength (l) = ax/D |
Electric current |
Acceleration = change in velocity/time taken |
Electrical energy |
Energy = VIt |
Electrical resistance |
Resistance (R) = voltage/current = V/I |
Force |
Force = mass x acceleration = d(mv)/dt |
