'The acceleration of a free falling body and gravity are the same thing' and 'acceleration and gravity have the same effect' CAN YOU PLEASE EXPLAIN THIS??

Answer 1

I can't explain the statement as stated. Gravity is a force, so it can not be an acceleration. g is the acceleration due to gravitational force near the surface of a large body (here, the earth). For a body in free fall and negligible air resistance, the net force is only it's weight = mg). Using the 2nd Law a = F_Net/m = mg/m = g. This is why all objects accelerate at g when they are in free fall near the earth's surface.

Answer 2

the standard equation for a position in space near the earth's surface is

h(t) = (a/2)t^2 + vot + ho where ho = initial height, vo = initial speed, a = the deceleration due to gravity = -32 feet per second per second = -9.8 meters per second per second

gravity is a peculiar force, which seems to operate at a distance, with no medium or field, seemingly instantaneously, faster than the speed of light, a limit that cannot be exceeded.

Scientific American had a 2007 article "The Illusion of Gravity"

Einstein's Relativity Theory postulated massless "gravitons" particle/waves like the massless photons of light. We've observed photons, but not gravitons. Einstien also predicted "gravity waves" similar to light or sound wave, but gravity waves also have never been never observed. For Einstein the curvature of space time explains "gravity." About 6 or so years ago, they thought they had discovered gravity waves, but retracted their less than peer reviewed article as the math and statistics weren't convincing enough.

Other forces in nature have been related, such as magnetism and electricity. But gravity remains more of an unexplainable mystery than it may appear.
