In introductory physics (SI units), what units is acceleration measured in?

• A. $\frac{m}{s^2}$
• B. $\frac{m}{s}$
• C. $N$
• D. $\frac{s^2}{m}$

Answer: (A)

Verified step by step guidance

1. Recall that acceleration is defined as the rate of change of velocity with respect to time.
2. Velocity itself is measured in meters per second, which is written as \(\frac{m}{s}\).
3. Since acceleration is the change in velocity per unit time, its units are velocity units divided by time units.
4. Expressing this mathematically, acceleration units are \(\frac{\frac{m}{s}}{s} = \frac{m}{s^2}\).
5. Therefore, in SI units, acceleration is measured in meters per second squared, or \(\frac{m}{s^2}\).
