A cheetah is now chasing an antelope. Before unleashing its speed, it silently sneaks up to the prey and when the distance is confident enough to attack ,the cheetah burst into running . Cheetah is the fastest animal on the planet, it can accelerate from 0 to 60 km/h within 3 seconds. Its speed is so fast that half of the time its legs don’t touch the ground.It uses its front paw trying totrip the prey. Cheetah’s long tail now functions as a rudder on a boat to keep balance.
