Which of the following is the SI unit for momentum?
A
B
C
D
Verified step by step guidance1
Recall the definition of momentum in physics: momentum (\( \vec{p} \)) is the product of an object's mass and its velocity, expressed as \( \vec{p} = m \vec{v} \).
Identify the SI units for mass and velocity: mass is measured in kilograms (kg), and velocity is measured in meters per second (m/s).
Combine these units according to the formula for momentum: multiply kilograms (kg) by meters per second (m/s) to get the unit for momentum.
Express the unit for momentum as \( kg \cdot m/s \), which means kilogram meter per second.
Compare this unit with the given options to determine which one matches the SI unit for momentum.
