How can the cat change its orientation and rotate without violating the law of conservation of angular momentum?

A cat’s ‘righting reflex’ is augmented by an unusually flexible backbone and the absence of a collarbone in the skeleton. Combined, these factors allow for amazing flexibility and upper body rotation. By turning the head and forefeet, the rest of the body naturally follows and cat is able reorient itself.

When a cat jumps from a height it stretches its body while landing justify the statement?

When a cat falls to ground from a height, it stretches its body alongwith the tail so that its moment of inertia becomes high. Since, Iω is to remain constant, the value of angular speed ω decreases and therefore the cat is able to land on the ground gently.

Can you turn in mid air?

Physicists assure us that an object in the air that is not turning cannot start to turn. They call this the law of conservation of angular momentum. However, a person in the air can turn to face a new direction without violating the law of conservation of angular momentum. I turn in midair and face that direction.

How do cats always fall on their feet?

Cats have a righting reflex, which allows them to turn while in the air, so that they land safely on their feet. Using their sensitive ears, they are able to maintain balance and orient themselves, so they are not injured from a fall.

What is the momentum of cat?

The motion of a free-falling cat’s center of mass is fixed and the overall system has an angular momentum of zero, so how does the cat not only turn itself over but stop turning so that it lands on its feet? There are two dominant models for the cat-righting reflex: “legs in – legs out” and “tuck and turn”.

Are cats gyroscopic?

Cats actually have a special internal gyroscope located in the inner ear that allows them to detect their position in space. While most mammals have to rely on sight, your cat’s internal gyroscope gives your cat a Yoda-like awareness of all things physics.

How does a cat land on its feet?

Cats have an inbuilt balancing system called the “righting reflex” that allows them to orient themselves and land on their feet.

How is a cat able to land on its feet after a fall?

Principle of conservation of angular momentum is followed by the cat. Since, Iω is to remain constant, and tretching out its legs increases its rotational inertia and thus the value of angular speed ω decreases and therefore the cat is able to land on the ground gently.

How do you turn mid air?

Jump into the air. Just as you become airborne, your assistant should point either to your left or right. Now, while you’re still in the air, quickly turn your body 90 degrees in the direction that your assistant pointed. (If you have no assistant, just decide in midair which way you will turn and then turn that way.)
