What is Simple Harmonic Motion in Physics
Simple Harmonic Motion in Physics
To and fro motion of a body in which acceleration is directly proportional to displacement and always directed towards mean position is known as Simple Harmonic Motion.
Condition for Simple Harmonic Motion
The conditions for simple Harmonic Motion are given below:
Some resisting force must act upon the body.
Acceleration must be directly proportional to the displacement.
Acceleration should be directed towards mean position.
System should be elastic
Following are the examples of S.H.M
– Body attached to a spring horizontally on an ideal smooth surface.
– Motion of a simple and compound pendulum.
– Motion of a swing.
– Motion of the projection of a body in a circle with uniform circular motion.
Note: Although some students, accustomed to school not to bother themselves, especially in the last grades, because they “will still be released”, they try to conduct the same policy in a higher educational institution. However, not here it was! New teachers are no longer good old teachers, they do not make concessions, and they are not going to make efforts for successful study of their wards. Here everything is grown-up, you need to understand where and why the study takes place. Otherwise, at the end of the first semester, for some part of the students, student life ends. And the atmosphere in the hostel? It’s unlikely that anything less favors the educational mood than this place! Evenings, which should theoretically be devoted to homework and preparing for a new school day, practically turn into mass festivities, the reason for which is with an enviable imagination. And fun and festivities in student hostels can not quickly end, they last until the morning. What here progress?
