Earth’s gravity speeds up a falling object by m/s for every second it drops

9.81

Explanation:

The acceleration due to gravity is a constant whose value is taken as 32.2 ft/s2 or 9.81 m/s2.

Considering the units given as m/s then the second option is correct. Any object falling down or thrown up experiences earth's gravity speed of 9.81 m/s for every second it drops or goes up. The existense of acceleration due to gravity is why a mango from a tree falls down instead of going up.

In conclusion, a falling object on earth experiences a speed of 9.81 m/s per second.
