Answer:
Generally the answer to your question is no. Cheetah lost all their weight as they evolved to run fast. They are now extremely light and are no match for a leopard. Indeed leopards as well as lions kill many young cheetah before they are old enough to do anything. This is why cheetah have evolved to have large litters as as little as 1 in 20 survive to have young of their own.
Cheetah can be driven off their kills by many animals, indeed there have been documented occasions when wart hogs (who are herbivores) have pushed cheetah off their kill. Part of their adaption to this is to hunt in the middle of the day when all the other predators are snoozing through the heat.
Finally also the previous answer states that they don't know but they could out run one- This is probably true but several things should be considered first.
A cheetah has been clocked at doing as much as 110 kmh, and can keep this up for as much as 700m though after this it will need at least 20 minutes to recover. A leopard has been known to do 90kmh or more but can only keep this up for 60-70m
However a leopard recovers faster. As such a cheetah could probably out run a leopard initially.
However cheetah occur at very low densities everywhere they live because they are so incapable of defending themselves and their meals. Kruger for instance in south Africa (about the size of wales) has a total of 200 or so cheetah, compared to 1000 lions and 1500 leopards
PREVIOUS ANSWER (ive left it but its useless)
I don't know, but they could out run one....I am more curious if a bear would beat a gorilla in a duel.
Why answer if you don't know???
Also a gorilla would never meet a bear in the wild. They are both very strong but it would depend on the type of bear and male or female gorilla
