Circular Motion — Tangential AccelerationMediumQuestion 30630

Question

If a particle in circular motion is speeding up, it has:
  1. A
    Only centripetal acceleration
  2. B
    Only tangential acceleration
  3. C
    Both centripetal and tangential acceleration
    Correct
  4. D
    Zero acceleration

Correct answer

Both centripetal and tangential acceleration

Explanation

Centripetal acceleration (a_c = v²/r) is always present for circular motion. A change in speed gives tangential acceleration (a_t = dv/dt). Both are present when speed changes.
