Conversely, a strong tailwind might add another 20 or so meters from a high enough height. That same jump into or with a strong wind from a height of say 10 or 12 meters only won't change the distance much, but will obviously change it some. "But now say you're jumping from a building. There is a large mass potentially stopping a tail wind.

Immediately, the gas begins to expand again, returning the ball to its normal shape. This action is a bit like a spring that causes the ball to bounce back into the air. How high a particular tennis ball will bounce depends upon the pressure of the air inside the ball. Scientists use a special equation to determine the amount of pressure: p=rRT ...
