How fast is gravity falling?

Could you elaborate on the concept of "gravity falling"? Are you referring to the acceleration due to gravity, or perhaps the speed at which objects are pulled towards a massive body like a planet? If it's the latter, gravity itself doesn't "fall"; it's a force that acts on objects, causing them to accelerate towards the center of a gravitational field. The rate of this acceleration, also known as the gravitational acceleration, is constant NEAR the surface of the Earth and is approximately 9.8 m/s² (or 32.2 ft/s²). So, in a sense, an object's speed towards the Earth's surface due to gravity increases at a constant rate, not that gravity itself is "falling." I hope this helps clarify your question.
