alleryWhich kind of motion happens when a fan blade rotates about its axis?
ATranslational motion
BRotational motion
CVibrational motion
DRandom motion
Answer & Solution
Correct answer: B. Rotational motion
1. Translational motion means every point of the body moves in a straight line.
2. Rotational motion means different points trace circular paths around a fixed axis.
3. A fan blade spins about its central axis, so each point moves in a circle around that axis.
4. Hence the motion is rotational.
