Question

Why is gravitational field strength equal to acceleration of free fall?

Answer 1

Answer:

As such, all objects free fall at the same rate regardless of their mass. Because the 9.8 N/kg gravitational field at Earth's surface causes a 9.8 m/s/s acceleration of any object placed there, we often call this ratio the acceleration of gravity.

Answer 2

This shows that the gravitational field strength is also the acceleration due to gravity on any object. This acceleration is the same for any object, regardless of mass. When considering small heights above the Earth's surface, such as those in our day-to-day experiences, g remains roughly constant.
