Kinesiology 2241A/B Lecture Notes - Lecture 21: Moment Of Inertia, Angular Velocity, Momentum
Document Summary
Angular momentum is the rotational inertia of an object multiplied by its angular velocity. Your magnitude and direction are the same while in the air until you hit the ground. Similar to linear momentum, this is the quantity of rotational motion in the object: Angular momentum is a measure of how hard it will be to stop the object rotating. Your axis of rotation is going to be the same while in the air until you hit the ground. Remember the radius of gyration and how we use it to find the rotational inertia. But how does angular momentum relate to torque. To change angular momentum we need to apply a torque (similar to linear momentum needs a force) You have no torque on you while you"re in the air, however as long as you have a foot on the ground you can correct your torque so that you land how you need to.
