Centripetal force is perpendicular to velocity, which is why the resulting circular motion is:
AUniform
BUneven
CUpward
DUnstable
Answer & Solution
Correct answer: A. Uniform
1. A force along the velocity would change the speed.
2. A perpendicular force only changes the direction.
3. So the circular motion stays uniform.
