Which of the following is the correct SI unit for momentum?
A
B
C
D
Verified step by step guidance1
Recall that momentum is defined as the product of mass and velocity, mathematically expressed as \(\mathbf{p} = m \mathbf{v}\).
Identify the SI unit of mass, which is the kilogram (kg), and the SI unit of velocity, which is meters per second (m/s).
Combine these units to find the SI unit of momentum: multiply kg by m/s, resulting in \(\mathrm{kg \cdot \frac{m}{s}}\).
Examine the given options and compare their units to the derived unit for momentum.
Conclude that the correct SI unit for momentum is \(\mathrm{kg \cdot \frac{m}{s}}\), as it directly corresponds to mass times velocity.
