Rotational Dynamics Rotational kinematics relates angular position, velocity, acceleration and time. Rotational dynamics deals with rotational energy, angular momentum, and torque.

Rotational Dynamics Newton’s First Law: a rotating body will continue to rotate at constant angular velocity as long as there is no torque acting on it. Picture a grindstone on a smooth axle. BUT the …

The rotational quantities behave exactly like their linear counterparts. Linear motion equations: Centripetal acceleration is a reaction to an external force. The force that causes an object to travel in …

Pull each string and compare the rotational acceleration for the apparatus shown on the left and right. The rotational acceleration is greater for the system on the left because the masses are closer to the …

In this lab, you will work to develop an understanding of how to model rotational motion and quantify several aspects in order to measure the moment of inertia of an object and compare to its theoretical …

Is there a “special” set of xyz axes for a given system? Yes! Possible (but difficult) to find “principal axes” such that products of inertia are zero → in this reference frame: L. directions! Notice L and ω don't …

When an object rotates about a spin axis through some angle, it changes its angular position (relative to some reference line). The direction of rotations is important. So angular position is a vector quantity. …
