Yo-yo physics

  1. May 29, 2005 #1
    So I have a project due Monday on the yo-yo. It is a bonus project.

    I just need to know what the linear momentum equation is for accelerating objects. And does anyone know of a *simplified* version of the angular momentum equation, like something out of Physics 12?

    Any help is appreciated

    Just apply Newton's second law both in normal (F=ma) and angular form (I*alpha=tau), where I is inertia of rotation, tau is torque and alpha is the tangential angular acceleration.
