Question

Linear simple harmonic motion define

Answer 1

Answer:

• A special type of periodic motion in which a particle moves to and fro about a mean position.
• The restoring force is always directed towards mean position and its magnitude at instant is directly proportional to displacement of the particle.

F α -x

F = - k x , k is force constant , and its SI unit is Nm⁻¹

Answer 2

Answer:

Definition :

(SHM) is defined Linear simple harmonic as the linear periodic motion 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.
