Recall that acceleration is defined as the rate of change of velocity with respect to time.
Velocity has units of meters per second (\(m/s\)), and time has units of seconds (\(s\)).
Therefore, acceleration units are obtained by dividing velocity units by time units: \(\frac{m/s}{s}\).
Simplify the expression to get the units of acceleration: \(\frac{m}{s^2}\).
Recognize that in the SI system, acceleration is expressed in meters per second squared (\(m/s^2\)).
