Here (all units see here):. The fixed axis hypothesis excludes the possibility of an axis changing its orientation, and cannot describe such phenomena as wobbling or precession. Khan Academy Physics 288,331 views. Rotational inertia of a body is a measure of its resistance to motion about some circular axis. particles 1) 1D 2) 2D 3) 3D B. Let's then use these as the foundation to learn about centre of mass, rotational motion, gravitation, solids, fluids, thermodynamics, and oscillations and waves. The distribution of mass matters here—these two objects have the same mass, but the one on the left has a greater rotational inertia, as so much of its mass is far from the axis of rotation. Before we study the theorems of parallel and perpendicular axis let us first see what moment of inertia is. ) Velocity vector (red) and position vector (blue) for an object executing uniform circular motion.
