Simple harmonic motion definition how to#

Learn the difference between Periodic and Oscillatory Motion here. Simple harmonic motion examples: the motion of a pendulum, motion of a spring, etc. Periodic motion examples are the motion of the hands of a clock, the motion of the wheels of a car, etc. In the simple harmonic motion, the displacement of the object is always in the opposite direction of the restoring force.Īlso, the periodic motion may or may not be oscillatory.Īnd, the simple harmonic motion is always oscillatory. In the periodic motion, the displacement of the object may or may not be in the direction of the restoring force. Difference between Periodic and Simple Harmonic Motion Periodic Motion Note: The period of simple harmonic motion does not depend on amplitude or energy or the phase constant.

Learn how to find Velocity and Acceleration of Simple Harmonic Motion here Epoch(α) is the phase at the beginning of the motion. is its state of oscillation, and the magnitude and direction of displacement of particles represent the phase. unit of frequency is hertz or r.p.s(rotations per second), and its dimensions are. is the number of oscillations that a particle performs per unit time. Thus, the motion will repeat itself after nT, where, n is an integer.

is the least time after which the motion will repeat itself.

Period: The time taken by a particle to complete one oscillation is its period.

Its S.I. unit is the meter, and the dimensions are.

Amplitude: The maximum displacement of a particle from its equilibrium position or mean position is its amplitude, and its direction is always away from the mean or equilibrium position.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.
