Question

The circular motion of a particle with constant speed is_​

Answer 1

Answer:

periodic but not SHM.

Explanation:

• For a motion to be SHM, it has to be small amplitude  and the acceleration is proportional to the displacement of the particle and directed against its displacement . Here the acceleration has centripetal and tangential components (here zerosince uniform circular motion) but has no variation with particle displacement  hence can be oscillatory but not in SHM.
• In circular motion of a particle with constant speed, particle repeats its motion after a regular interval of time but does not oscillate about a fixed point. So, motion of particle is periodic but not simple harmonic.
