Chapter 7 - Oscillations - 5


Physics Class 11
1. In vibratory motion, velocity of a particle is maximum at the extreme position.


2. The string of simple pendulum should be light and extensible.


3. The reciprocal of frequency is called time period.


4. For a particle executing SHM, its maximum displacement from mean position is called instantaneous displacement.


5. Soldiers rhythmic march may set up oscillations of dangerously large amplitude in the bridge structure.


6. Projection of a particle moving with constant speed in a circle does not show S.H.M.


7. The velocity of a particle moving in circular path is directed sometimes along the tangent


8. In the absence of frictional effects, the mechanical energy of a system executing S.H.M. changes with time.


9. An application of simple oscillations is the shock absorber of a car.


10. In S.H.M, the magnitude of restoring force is independent of displacement from mean position.
