FSC, ICS (Part 1) Physics Short Questions (Chapter #7)Short QuestionsQ.7.1. Name two characteristics os simple harmonic moi on?Ans. Two characteristics of simple harmonic motion is given below.(i) Acceleration of abody executing S.H.M is directly proportional to the displacementshown by the equation.and directed towards the mean position asCalculating frequencyrelation shows that -equency does not depends upon amplitude it depends upon the length of the simple pendulum.Similarly for spring mass system.also shows that frequency only depends upon the mass and not on the amplitude.Q.7.3. Can we realize an ideal simple pendulum*Ans. No we cannot realize an ideal simple pendulum for ideal simple pendulum conditions must be fulfilled.Bob r ust be very small (point mass).The suspension string must be weightless and inextensible. must be friction less.
