They don't. They jump higher and further because they are stronger and better at doing so, not because they can resist gravity.
Gravity is not "used". In gymnastics, gymnasts almost defy-gravity by flipping in the air but have no control of what gravity does.
Yes. Gymnasts learn gravity way before they learn it in school!! We have to learn that when doing a flip you have to set (shoot up in a strait body really fast) before flipping so the gravity doesn't pull you down before the flip is done!
yes
No
The plural of defy is defies. As in "this defies the laws of gravity".
Magnets do not defy gravity, but they can create forces that appear to defy gravity. When a magnet is placed near an object, it can create a magnetic force that opposes the force of gravity acting on the object. This can make the object appear to levitate or hover.
The chemical that is called defying gravity.
Ultimately, no.
They cannot.
The anti-gravity wheel uses magnets to create a repelling force that counteracts gravity, allowing the wheel to levitate and appear to defy gravity.
The water seemed to defy gravity.
No.
