I've been searching for the relation between the spinning speed and inertia in equation form. I do know that since the skater inertia is smaller the spinning speed is faster but that about it. Any hint would be helpful. One more thing, is angular velocity and angular speed the same thing?
Do your notes have anything on angular momentum? If not, try g**gling it.Ys VL said:
Looks right - but you should always include the units in the answer, or better still at every step in the calculation.Ys VL said:I'm back,
I looked up angular momentum. From what I can tell if I calculate L (angular momentum) I should have no problem solving this since L is suppose to be constant and the tangential velocity is given for it's final and initial. I tried it and I think I finally got it. If this is right thanks haruspex, if not... what else do you think I should look up?
Did I do it correctly?
No, inertia and angular speed are two separate quantities and cannot be directly calculated from one another. Inertia is a measure of an object's resistance to changes in its motion, while angular speed is the rate at which an object rotates.
Angular speed does not directly affect inertia. However, an object with a higher angular speed will have a greater rotational kinetic energy, which is related to its inertia.
No, measuring an object's angular speed does not provide enough information to determine its inertia. Other factors such as mass and shape also play a role in an object's inertia.
No, inertia and angular momentum are two distinct concepts. Inertia is related to an object's resistance to changes in its motion, while angular momentum is a measure of an object's rotational motion.
Inertia and angular acceleration are related through the moment of inertia, which is a measure of an object's resistance to changes in its rotational motion. The greater the moment of inertia, the greater the object's resistance to angular acceleration.
