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

Newton’s Laws of Motion work so well for translational motion that we should use them as a model of the laws for rotational motion. The idea here is to change the laws as little as possible, but still …

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 …

Apr 2, 2024 · In complete analog to the work energy theorem for the translator motion, it can be stated for rotational motion as: Wrot= Krot The net rotational work done by the forces is equal to the …

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 …

In the last unit we developed the vector equation that determines rotational dynamics, that the net torque on a system of particles about a given axis is equal to the product of the moment of inertia of …

LINEAR AND ROTATIONAL MOTION Until now, we have only considered motion of an object without rotation. The whole object, regardless of its shape, was reduced to a single point which could be …
