Conservation of angular momentum

AI Thread Summary
Conservation of angular momentum applies when there is no net torque acting on a system, allowing for the analysis of rotational motion. This principle can be quantitatively determined by equating the initial and final angular momentum of a system. An example often discussed involves a figure skater pulling in their arms to spin faster, illustrating the conservation law in action. Additional resources and threads provide further examples and explanations to enhance understanding. Mastery of this concept is essential for solving related physics problems effectively.

Hi,
I am by now very used to the concept of conservation of momentum and energy, however i had never solved a problem using the conservation of angular momentum.
Well, in the case where angular momentum is conserved, we do not have a torque net. But, how this conservation law helps us to determine quantitatively ?
Could you illustrate the concept with an example?
Thank you very much.

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
