Why Are Cheetahs the Fastest Land Animal?

The video explains why cheetahs are the fastest land animals, despite their size. It delves into muscle types, highlighting the difference between slow and fast twitch fibers. The relationship between size and speed is explored, revealing that medium-sized animals often achieve higher speeds. A model predicting animal speed based on body size is introduced, applicable to various species, including extinct ones. The video concludes with a discussion on the cheetah's unique physical traits that contribute to its speed.

Why might larger animals like the T. rex not be as fast as smaller animals like the cheetah?

• They have longer legs which slow them down.

• They have more slow twitch muscle fibers.

• Their fast twitch muscles run out of fuel quickly.

• They lack sufficient muscle mass.

What does the model developed by researchers in 2017 predict?

• The intelligence of animals based on their brain size.

• The lifespan of animals based on their size.

• The maximum speed of animals based on their body size.

• The diet of animals based on their habitat.

Which of the following is NOT a feature that contributes to the cheetah's speed?

• Short legs

• Swiveling hips

• Flexible spine

• Large heart and liver

How does the cheetah's spine contribute to its speed?

• It reduces energy consumption.

• It maximizes the length of its stride.

• It provides better balance.

• It allows for greater muscle mass.

What advantage does the cheetah have over the leopard despite being similar in size?

• Larger paws

• More flexible spine

• Thicker fur

• Stronger jaw muscles
