Learn the difference between Linear and Damped Simple Harmonic Motion here Concepts of Simple Harmonic Motion (S.H.M) Here, k/m = ω 2 ( ω is the angular frequency of the body) Learn how to calculate Energy in Simple Harmonic Motion here Linear Simple Harmonic Motion Here, k is the constant called the force constant.
Therefore, the restoring force will be F= – kx (the negative sign indicates that the force is in the opposite direction). Now, let the force be F and the displacement of the string from the equilibrium position be x. In each case, we can see that the force exerted by the spring is towards the equilibrium position, this force is called the restoring force. And, if we push the spring inwards, there is a force exerted by the string towards the equilibrium position.If we pull it outwards, there is a force exerted by the string that is directed towards the equilibrium position.When there is no force applied to it, it is at its equilibrium position. Now, consider there is a spring that is fixed at one end. Oscillations of a pendulum are an example of simple harmonic motion. Simple Harmonic Motion Definition – Simple harmonic motion is the motion in which the object moves to and fro along a line.įor instance, Have you seen a pendulum? When we swing it, it moves to and fro along the same line. Browse more Topics under Oscillationsĭownload the Cheat Sheet of Oscillations below Simple Harmonic Motion is a great example of an oscillatory motion. In these examples, the particle performs the same set of movements again and again in a periodic motion, and oscillation is one such set of movements. For example, the motion of the hands of a clock is a periodic motion, the rocking of a cradle, swinging on a swing, leaves of a tree moving to and fro due to wind breeze, and so on. We see many examples of periodic motion in our day-to-day life. Now, we need to know what periodic motion is, so as to understand simple harmonic motion. Periodic motion is the motion that repeats itself in equal intervals of time.
