The dimensions of the following physical quantities are as follows:
1. Moment of a couple: [moment of force] = [force] x [distance] = [M] x [L] = [ML^2T^-2]
2. Power: [power] = [work] / [time] = [force] x [distance] / [time] = [M] x [L^2] x [T^-3]
3. Momentum: [momentum] = [mass] x [velocity] = [M] x [L] x [T^-1]
4. Velocity: [velocity] = [distance] / [time] = [L] / [T]
5. Density: [density] = [mass] / [volume] = [M] / [L^3]
