What is the acceleration due to gravity on Earth?

• A. 9.81 meters per second squared.
• B. 32.2 feet per second squared.
• C. 9.8 feet per second squared.
• D. 3.2 feet per second squared.

Answer: (B)

Gravity near Earth’s surface causes a constant downward acceleration, called g, which is about 9.81 m/s^2. When you express the same value in feet per second squared, you convert meters to feet (1 m ≈ 3.2808 ft), giving g ≈ 9.81 × 3.2808 ≈ 32.174 ft/s^2, commonly rounded to 32.2 ft/s^2. So the correct match in the given units is 32.2 ft/s^2. The same physical quantity can be written as about 9.81 m/s^2 in metric units, illustrating the unit conversion. The smaller numbers or the same value with the wrong unit don’t fit the standard magnitude of g.
