"How do you know this to be true? Because the internet told you? because you read it in a book? Even if what you read was correct, you should then ask are their any other variables that can change this formula? "
Because I took an object and dropped it through a set of laser gates which measured the time it took to fall and the velocity of the object at different points. I then used the data to calculate the rate of acceleration. The answer I got was within tolerances I would expect of the accepted answer, providing for errors in significant figures and small errors in the equipment. Because of this I find the answer of 9.807m/s•s to be credible.
"What if i told you the gravitional rate on earth increases when the drag coefficient decreases? so to say "The gravitational acceleration rate on Earth is 9.8 m/s²" is at best an estimation. because the higher up you go the higher the gravitional rate will increase up to an objects terminal velocity. as the atmosphere thickens more drag is applied and the terminal velocity will decrease and the acceleration rate will also decrease the closer one gets to sea level..."
Hahaha!!!
No.
The rate of acceleration due to gravity decreases the further you get from sea level. I have a very nice potential energy curve in my physics book that shows this. The air resistance is a completely different factor, a differential that decreases with an increase in altitude. The reason you might assume as you do is because the rate at which the air resistance differential approaches zero is greater than the decrease in the change in acceleration due to gravity.
Physics nitpicker, away!!!
