Question

State and explain the principal of conservation
of angular momentum use a suiteble
Allustration Doce use it in our daily life?
when ?​

Answer 1

Explanation:

The law of conservation of angular momentum states that when no external torque acts on an object, no change of angular momentum will occur.

Let us consider some examples of momentum: the Earth continues to spin at the same rate it has for billions of years; a high-diver who is “rotating” when jumping off the board does not need to make any physical effort to continue rotating, and indeed would be unable to stop rotating before hitting the water. These examples have the hallmarks of a conservation law. Following are further observations to consider:

1. A closed system is involved. Nothing is making an effort to twist the Earth or the high-diver. They are isolated from rotation changing influences (hence the term “closed system”).

2. Something remains unchanged. There appears to be a numerical quantity for measuring rotational motion such that the total amount of that quantity remains constant in a closed system.

3. Something can be transferred back and forth without changing the total amount. A diver rotates faster with arms and legs pulled toward the chest from a fully stretched posture.

thanks,hope you got the answer,mark as brainliest and follow me !!
