7.1: Name two characteristics of SHM.

SHM is caused by restoring force. It has following two characteristics.

Acceleration of the body executing SHM, is proportional to its )

displacement and is directed towards mean position always i.e. a « -x

Any object/body that is executing SHM, must trace sine cure. )

7.2: Does frequency depends on amplitude for harmonic oscillators?

General formula for frequency of SHM is f= (for simple pendulum,

f= T and for mass-spring system, f=m.There is no amplitude

found in any of above. So frequency does not depend upon amplitude of

simple harmonically vibrating system.
