The Grizzly Bear

through my research i have found that the very large and hulking grizzly is amazingly fast for a creature its size.  grizzly bears have been clocked at speeds of about 30 MPH and are are able to maintain this as a constant speed for 100 yards or more. many people who observe and study these animals claim that a grizzly would be able to out run most race horses in a 100 yard distance.

I have yet to find an explanation for why these huge animals are able to run this fast.

The Cheetah

most people are already aware that the cheetah is the fastest land animal.  it can reach a top speed between 70 and 75 mph, but is unable to maintain that spped for very long, and is able cover about 460 meters in that short time.  the cheetah does however have an excellent acceleration time being able to transition from a staionary position to running at a spped of about 64mph in 3 seconds.

The Timber Wolf

the timber wolf aslo know as the gray wolf is a surprisingly fast predator with the ability to run at speed up to 35mph.  it can also cover 16ft in a single and maintain a constant speed of about 20mph over an extended period of time.  which leads me to believe that the wolf has a great deal of stamina.

predators chosen

the three predators i have chosen to compare are the Timber Wolf, Cheetah, and Grizzly Bear.
I will be doing research on these three predators so I can determine which is the best in terms of physics.
bite force, weight, speed, ability to change direction and flexibilty.
