Simple linear harmonic motion
Answers
Answer:
Simple Harmonic Motion or SHM is defined as a motion in which the restoring force is directly proportional to the displacement of the body from its mean position. The direction of this restoring force is always towards the mean position.
Linear Simple Harmonic MotionDefinition – The linear periodic motion of a body in which the restoring force is always directed towards the equilibrium position or mean position and its magnitude is directly proportional to the displacement from the equilibrium position. Also, all simple harmonic motions are periodic in nature, but all periodic motions are not simple harmonic motions.Now, take the previous example of the string. Let its mass be m. The acceleration of the body will be,a = F/m = – kx/m = – ω2xHere, k/m = ω2 (ω is the angular frequency of the body)
