### Ball Rolling on Tilted Turntable

Ball Rolling on a Rotating Turntable (The following examples are from Milne, Vectorial Mechanics.) A sphere is rolling without slipping on a horizontal plane. The plane is itself rotating (about a fixed vertical axis) at constant angular velocity . Problem: Find the path of the center of the sphere, for given initial position and velocity. We have three vector equations: Newton's equations ...

### What is the angular momentum of a 0.150kg ball rotating on ...

Mar 11, 2013 · The formula for angular momentum is: L = Iw, where I = the moment of inertia of a solid sphere ((2mr^2)/5) and w = the angular velocity. So the moment of inertia of the ball is (2(.150)(1^2)/5) = .06. Using the formula above you get: L = Iw = (.06)(12.8) = .768 rad x kg/s

### Linear Speed Formula (Rotating Object)

Linear Speed Formula (Rotating Object) The linear speed of a point on a rotating object depends on its distance from the center of rotation. The angular speed is the angle that an object moves through in a certain amount of time. The angular speed has units of radians per second (rad/s). There are 2π radians in .

### Rolling Ball Dynamics - Freie Universität

is modiﬁed according to the formula ... at velocity v0 and no rotation. When the ball reaches a state of rolling without slipping, the rolling velocity vr is related to the rolling angular velocity ωr by vr = ωrR and therefore we have vr −v0 = − 2 5 vr From this we obtain vr = 5 7v0. This means, that the rolling velocity is always ﬁve sevenths of the original velocity regardless of ...
