Recall that velocity is defined as the rate of change of displacement with respect to time.
Displacement is measured in meters (m) in the SI system, and time is measured in seconds (s).
Therefore, velocity is measured in meters per second, which can be written as \(\frac{m}{s}\).
Review the other units given: Newtons (N) measure force, meters per second squared (\(\frac{m}{s^2}\)) measure acceleration, and Joules (J) measure energy.
Conclude that the correct SI unit for velocity is meters per second (\(\frac{m}{s}\)).
