The rotation angle is described as analogous to which linear quantity?
ALinear distance
BLinear dentist
CLinear density
DLinear daylight
Answer & Solution
Correct answer: A. Linear distance
1. Rotational quantities are introduced by pairing them with linear ones.
2. The rotation angle measures how far around something has turned.
3. The rotation angle is the amount of rotation and is analogous to linear distance.
4. So the pairing is with linear distance.
