Question

The circular motion of a particle with constant speed is

• A. Periodic but not SHM
• B. SHM but not periodic
• C. Periodic and also SHM
• D. Neither periodic nor SHM

Answer 1

The correct option is A Periodic but not SHM

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.
