Question

What is the approximate acceleration of gravity of Earth at Earth's surface?

1) 10 km/s2 downward
2) 10 m/s2 downward
3) 10 km/s downward
4) 10 m2/s downward
5) 10 m/s downward

Answer 1

The approximate acceleration of gravity on Earth's surface is 9.80 m/s² downward, with the rounded answer being 10 m/s² downward.

Step-by-step explanation:

The approximate acceleration of gravity of Earth at Earth's surface is 9.80 m/s² downward. Therefore, the closest option to the actual value is 10 m/s² downward. This value is often rounded for simplicity in calculations, but the actual average acceleration due to gravity on Earth is approximately 9.80 m/s². This value slightly varies depending on factors such as latitude, altitude, and local geographical formations, but for many calculations, 9.80 m/s² or the rounded value of 10 m/s² is used unless more precision is required.
