SHM (simple harmonic motion) for 5 marks ??
Answers
Shm...... ██████▓
When an object moves to and fro along a line, the motion is called simple harmonic motion. Have you seen a pendulum? When we swing it, it moves to and fro along the same line. These are called oscillations. Oscillations of a pendulum are an example of simple harmonic motion.
Answer:
Definition
(SHM) is defined Linear simple harmonic as the linear periodic motion motion ofa body, in which the force (or acceleration) is always directed towards the mean position and its magnitude is proportional to the displacement from the mean position.
OR
A particle is said to execute linear SHM if the particle undergoes oscillations about a point of stable equilibrium, subject to a linear restoring force always directed towards that point and whose magnitude is proportional to the magnitude of the displacement of the particle from that point.
Examples : The vibrations of the tines (prongs) of a tuning fork, the oscillations of the needle of a
sewing machine.
