Cheetah tracking study reveals incredible acceleration

Words I didn't know:

Speed: velocitat

Prey: oren

stride: pas

Summary:

Cheetah is the fastest animal in the world. People think that this animals uses all  of their speed to capture their pray, but it isn’t true, their big factor to capture their pray is thanks their acceleration and faster changes in speed. For example, cheetah can change their speed with only a single stride more or less 7mph.

Opinion:

I always I’m asking this question, how cheetah are the best runner? Maybe, because his body is so thin, his legs are longer than other animals, his weigh is poor..  But all of this characteristics other animals have too, for example a deer, a gazelle, a wolf, a fox.. But, why cheetah is the best? Now, with this new I find my answer, the acceleration!
