The dimensional formula of momentum depends on the system of units being used. In the International System of Units (SI), momentum is defined as the product of mass and velocity. The dimensional formula for momentum in SI units is:
[M][L][T]⁻¹
Where: [M] represents the dimension of mass (kilogram, kg) [L] represents the dimension of length (meter, m) [T]⁻¹ represents the dimension of time (inverse second, s⁻¹)
Therefore, the dimensional formula for momentum in SI units is kilogram meter per second (kg·m/s).
