Define linear simple harmonic motion.

1.	Define linear simple harmonic motion.
Answer» Definition: Linear simple harmonic motion (SHM) is defined as the linear periodic motion of a 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.
