Some of the real-world applications of SHM are as follows: These solutions can be easily verified by substituting the value of x in the differential equation.Īny object which repeats its motion over a period of time, to and fro about a mean position, executes simple harmonic motion. X = Asin(ωt+ϕ) (When the particle is at point Q in figure ‘b’ shown above (at any time t). X₀ = Asinϕ, it is the solution for the particle when it is in any other position but not in the mean position in figure (b). X = Asinωt, it is the solution for the particle when it is in its mean position point ‘O’ in figure (a). The solutions of simple harmonic motion differential equation are given below: Simple Harmonic Motion Differential Equation The frequency of oscillatory motion is given by, The frequency of an object exhibiting Simple Harmonic Motion is the number of oscillations that it undergoes per unit amount of time. The time taken by an object to finish one oscillation is called its time period. The negative sign denotes that the restoring force acts in the opposite direction. Let the force exerted by the spring be ‘F’, and the displacement of the spring from the equilibrium position be ‘x’. In both cases, the force given by the spring is towards the equilibrium position. If we push the spring inwards, a force is generated on it, which is directed towards the equilibrium position. If we pull the spring outwards, then a force is exerted by the spring, which directs it towards the equilibrium position. The spring remains in its equilibrium position when no force is applied to it. Let us consider a spring fixed at one end. Let the speed of the particle be ‘v0’ when it is at position p (at a distance x₀ from the mean position O).Īt t = 0, the particle is at point P (moving towards the right direction).Īt t = t, the particle is at point Q (at a distance x from O). Let the mean position of the particle be O. We can calculate the energy in SHM simple harmonic motion.Ĭonsider a particle of mass ‘m’ exhibiting Simple Harmonic Motion along the path x O x. The unit of spring constant/force constant is N/m in the S.I system and dynes/cm in the C.G.S. The negative sign indicates that the force is exerted in the opposite direction. Then the restoring force will be, F = - kx. Now, if the force is ‘F’ and the displacement of the spring from its equilibrium position is ‘x’. The force exerted by the spring is to attain its equilibrium position. If we push the spring inwards, a force is generated to bring it to its equilibrium position. If we pull the spring outwards, a restoring force is generated on the spring, which pulls it inwards towards the equilibrium position. If no force is applied to the spring, it remains in the equilibrium position. Let us consider a spring that is fixed at one end. These movements of pendulums are called oscillations, which show simple harmonic motion. It swings to and fro about its mean position where the string and the bob undergo the motion. A pendulum undergoes simple harmonic motion. The motion of an object that moves to and fro about a mean position along a straight line is called simple harmonic motion.
