    The choice of the symbol
    L to represent angular momentum in physics comes from historical conventions and mathematical convenience.
    Here are a few reasons why L is commonly used to represent angular momentum:
    Consistency with Linear Momentum: In many physics textbooks and courses, linear momentum is denoted by
    p. Using a different letter for angular momentum helps to distinguish it from linear momentum. The letter
    L was likely chosen to maintain consistency with the letter
    p, as it is a prominent letter in the Latin alphabet.
    Connection to the Term "Angular": The letter L may be chosen to represent angular momentum because it resembles the shape of a spinning object. When you think of an object rotating or spinning, it often forms a circular or angular shape, which aligns with the use of the letter
    L to represent angular momentum.
    Mathematical Convenience: In mathematical equations and formulas,
    L is a convenient letter to use because it is clear and easy to distinguish from other symbols. It also doesn't have any specific meaning attached to it, allowing it to be used in various contexts related to angular momentum without confusion.

    The use of "L" for angular momentum actually stems from the Latin term "impetus laevis," meaning "smooth tendency to motion."

    Can you explain the most efficient way to swing a golf club fast? For a right handed player, is it correct to consider the left shoulder as the center of a circle? Then… the left arm and club shaft as the radius of that circle? Finally, is the club head itself that thing that should be considered on the perimeter of that circle that has to be moved fast? Thank you for your consideration.

    Excellent efforts...great video...but one question..can we replace w( omega) by just V/R ...V is a quantity ( velocity) from linear velocity ,say V =ds/dt...., but omega (w) = d(theta)/dt...isn't it?
    \omega=\frac{\Delta \theta}{\Delta t}
    {\omega} = angular velocity
    {\Delta \theta} = change in angular rotation
    {\Delta t} = change in time

    When we change others' angular values to linear we divide by R( like W=V/R, alpha = a/R..... )but here we multiply by R (PxR)and why is that?

    if you decrease the mass instead of decreasing the radius, it wouldn't be conservation of angular momentum, would it?
    like if I'm on a spinning chair with hands outstretched, holding 2 masses in my hands. If I drop the 2 masses while spinning, my angular velocity should stay the same, right? since the 2 masses take away some of the momentum while dropping the masses, and no net torque was actually acting on me spinning

    Just to let you know, angular energy is conserved, not angular momentum. Your derivation of COAM makes the assumption that I is constant which is not the case for a variable radii system. www.baur-research.com/Physics

    • @rodneyramcharitar2300
      @rodneyramcharitar2300 3 года назад

      The example of a figure skater pulling his/her arms in is an example of reducing radius/I…hence the increase in angular velocity. Angular momentum by definition is conserved

    • @TheAnimammal
      @TheAnimammal 3 года назад

      @@rodneyramcharitar2300 Nonsense. Something cannot be "conserved by definition". Especially when it is not conserved in reality. A figure skater "spins faster" because angular energy is conserved and if you measure her, you will find this to be the case and that she is far too slow to be conserving angular momentum and actually disproves conservation of angular momentum.

    • @carultch
      @carultch 2 года назад

      @@rodneyramcharitar2300 This man has an agenda to spread misinformation. He did an experiment where he pulled in a spinning object by a string through a tube and found that the results were inconsistent with what conservation of angular momentum would predict. The reason is friction and drag apply external torques to the system, along with unintentional torques that his other hand applied to the system, which is why it didn't get to the speed that conservation of angular momentum would predict. He thinks it is kinetic energy that is conserved instead of angular momentum, but refuses to accept that there is work done on a rotating system to redistribute its mass closer to the center, which would explain why kinetic energy can increase. There are experiments that do a better job of controlling for external torques by moving two masses together to avoid imbalance, and reducing the influences of outside torques, and the results are consistent with conservation of angular momentum.
