Five things that help a cheetah are long legs, a springy back bone, a slender build, a long tail, and long claws. Long legs and a springy back bone help cheetahs take the longest possible strides. Aslender build is good for running because the bigger a cheetah is, the faster it can go. Along tail helps the cheetah keep balance while running at top speeds. It also helps for sharp turns.
Long claws help cheetahs as they grip the ground as they run.
The claws of a cheetah works like a track shoe. They dig into the ground as the cheetah pushes off and help to build up speed faster. Cheetahs are the only big cats that can always keep their claws extended. A cheetah's paws are more likely to look like a dogs paws because they are always extended. A long time ago people thought cheetahs were part of the dog family.
