Per NCERT §6.1.1, a rigid body's general motion can be decomposed into which two kinds?
ATranslation of CM + rotation about CM
BPure translation alone for rigid bodies
CPure rotation alone (no translation)
DRandom vibration alone
Answer & Solution
Correct answer: A. Translation of CM + rotation about CM
NCERT §6.1.1: any rigid body motion = translation of CM + rotation about an axis through CM. Rolling cylinder is the canonical example.
