Periodic motion is motion of an object that regularly return to a given position after a fixed time interval. We can identify several types of periodic motion in everyday life. We return to the dinner table every night. The earth returns to the same position in its orbit around sun each year. A special Kind of periodic motion occurs in mechanical systems when the force acting on an object is proportional to the position of the object relative to some equilibrium position, the motion is called simple harmonic motion, which is the primary focus of this chapter. Do check out chapter wise Physics Questions prepared by Physics Wallah.
The end–of–chapter problems are categorized into five section, namely Exercise – I (objectives where only one of the option is correct), Exercise – II (objectives where more than one option may be correct), Exercise – III (matrix matches and paragraph type questions), Exercise – IV (subjective questions), Exercise- V (old JEE questions) to help the student assess his understanding of the concept and further improvise on his problem solving skills. Solutions to all the questions in the booklet are available and will be provided to the students (at the discretion of the professor). Every possible attempt has been made to make the booklet flawless. Any suggestions for the improvement of the booklet would be gratefully accepted and acknowledged.
