PHYS111Q : Homework Assignments

Rolling, angular momentum, equilibrium

Goals :

Apply the law of conservation of energy to objects rolling without slipping.
Calculate the angular momentum of an object

$\begin{displaymath} L = I \omega \end{displaymath}$

or particle

$\begin{displaymath} L = m v r \sin \phi \end{displaymath}$
Apply the law of conservation of angular momentum

$\begin{displaymath} \Delta L^\mathrm{sys} = 0 \end{displaymath}$

to rotational collisions.
Determine the forces and torques acting on a system in equilibrium,

$\begin{displaymath} \tau^\mathrm{net} = 0 \hspace{2cm} \vec{F}^\mathrm{net} = 0 \end{displaymath}$
