How are cheetahs so fast?

Have you ever raced a cheetah? Hopefully not, that sounds dangerous. But if you have, that cheetah probably left you in her dust. We asked Rick Schwartz from the San Diego Zoo to help us figure out why cheetahs are so fast. Got a question that’s testing you? Send it to us at BrainsOn.org/contact, and we’ll help you find an answer so you don’t have to be a cheetah!
