WebIn this section, we work with these definitions to derive relationships among these variables and use these relationships to analyze rotational motion for a rigid body about a fixed … WebWhen objects rotate about some axis—for example, when the CD in Figure 6.2 rotates about its center—each point in the object follows a circular path. Figure 6.2 All points on a CD travel in circular paths. The pits (dots) along a line from the center to the edge all move through the same angle Δ θ in time Δ t .
