As per your syllabus, the centripetal acceleration vector in UCM is which kind of vector?
AConstant magnitude, changing direction
BBoth magnitude and direction constant
CChanging magnitude, constant direction
DConstant magnitude, constant direction
Answer & Solution
Correct answer: A. Constant magnitude, changing direction
Your syllabus: |a_c| = v²/R is constant in UCM, but its direction (toward centre) rotates with the particle. Not a constant vector.
