The unit used to measure acceleration is the _____.

• A. G
• B. Newton
• C. Meters per second squared
• D. Pound

Answer: (A)

In aviation contexts, acceleration is often described using multiples of Earth's gravity, called G's. This unit is convenient because it tells you how strong the acceleration feels relative to your weight. One G equals 9.81 m/s^2, so 2 G is about 19.62 m/s^2, 3 G about 29.43 m/s^2, and so on. The other options aren’t used to express acceleration in the typical sense: a Newton and a Pound are units of force, not acceleration, and meters per second squared is the SI unit for acceleration but the question’s phrasing and common flight terminology emphasize the G-unit.
