A9.80 m/s^2
B1.67 m/s^2
C6.67 m/s^2
D98.0 m/s^2
Answer & Solution
Correct answer: A. 9.80 m/s^2
1. The acceleration of a freely falling object is called the acceleration due to gravity.
2. Its magnitude is given its own symbol and has the average value 9.80 m/s^2 on Earth.
3. That value is constant at any given location on Earth.
4. The figure 1.67 m/s^2 is the value on the Moon, not on Earth.
