Website (Physics Hypertextbook): Rotational Dynamics; Rotational dynamics is Rotational Inertia Demo: Disk Roll & Balance stick. If a rigid body is rotating about a fixed axis, the particles will follow a circular path. It is also significant in the earth sciences, especially meteorology, physical geology, and oceanography, in that the Earth is a rotating frame of reference, and motions over the surface. Landing on slope b 13 of 21. Chapter 10 Dynamics of Rotational Motion 10. Now you will learn how to solve problems that have bodies that consist of many particles For this type of problem you will have to use kinematics of a rigid body instead of kinematic of a particle. Mass moments of inertia have units of dimension ML 2 ([mass] × [length] 2). In this module, we will examine Torque and Moment of Inertia (the rotational analogs of force and mass) and Newton's Second Law for Rotation. In which case is the torque due to the force about the rotation axis biggest? A. • A mechanical system with a rotating wheel of mass m w (uniform mass distribution).
