Explanation

Momentum is defined as the product of an object's mass and velocity:

momentum=mass×velocity\text{momentum} = \text{mass} \times \text{velocity}

  • Mass is measured in kilograms (kg)

  • Velocity is measured in meters per second (m/s)

So the unit becomes:

kg⋅m/s\text{kg} \cdot \text{m/s}

This unit describes the quantity of motion an object has and is a vector quantity, meaning it has both magnitude and direction.
