Solution for Homework 20 Motion in a Circle II Solution to Homework Problem 20.1() Problem: What does rotational inertia measure? Solution Rotational inertia is a measure of an object’s ability to resist changes in rotational velocity. Total Points for Problem: 2 Points Solution to Homework Problem 20.2() Problem: What is the unique diFerence between angular momentum and linear momentum? Solution Angular momentum depends not only upon mass and velocity (as does linear momentum) but also upon the distance between the object’s center-of-mass and the axis of rotation. So angular momentum contains an implicit reference to

Unformatted text preview: some xed point about which L has been calculated. or example, for a particle of mass m in uniform circular motion with radius R and with linear speed v , we can write L = I = ( mR 2 ) p v R P = mRv Total Points for Problem: 1 Points Solution to Homework Problem 20.3() Problem: What does angular momentum measure? Solution Angular momentum is a measure of an objects capacity to change the rotational motion of another object (just as linear momentum is a measure of an objects capacity to change the linear motion of another object). Total Points for Problem: 2 Points...
