air balloon center change changing figures fill hot inertia moment physical properties shape
It's like making figures out of balloons. You can fill a balloon with air and shape it to be a pretzel, a donut or a hot dog. Each will have a different moment of inertia and a different center of gravity. By changing the shape of the balloon, you change the physical properties of the balloon.
affect amount anywhere ball changing effect far flight increasing middle move stick weights
It's like a teeter-totter. If you want the other end to go up, you don't just stick two dumbbells in your hands. You move as far away from the middle as possible. By increasing that dimension, we get more effect than any amount of weights we could put anywhere else. No amount of weight you move will affect ball flight as much as changing geometry.
