Recall the definition of momentum in physics: momentum \(p\) is given by the product of mass \(m\) and velocity \(v\), so \(p = m \times v\).
Identify the SI unit of mass \(m\), which is the kilogram (kg).
Identify the SI unit of velocity \(v\), which is meters per second (m/s).
Since momentum is mass times velocity, multiply their units: \(\text{kg} \times \frac{\text{m}}{\text{s}}\).
Conclude that the SI unit of momentum is kilogram meter per second, written as \(\text{kg} \cdot \frac{\text{m}}{\text{s}}\).
