Is this why we have topics on kinematics of particles for which we say that rotation about mass centre is neglected? When we have a rigid body like a disc turning on a shaft and we write the equation of motion $J\ddot{\theta} + k\theta=0$, the disc is then assumed to consist of many particles but with each particle without any rotation about its own axis? Is this correct? | |
