The branch describing the motion of a rotating rigid body about a fixed axis is rotational:
AKilometrics
BKinetics rate
CKilowattage
DKinematics
Answer & Solution
Correct answer: D. Kinematics
1. It describes motion without asking what causes it.
2. The rotating body turns about a fixed axis.
3. That branch is rotational kinematics.
