The equation of motion of a particle in simple harmonic motion is given by :x(t) =0,2cos(wt), where x is in meter and t is in seconds. At x=0,the particle's velocity is v=-1,256 m/s. The period of oscillation, t, equals?

Definition Definition Special type of oscillation where the force of restoration is directly proportional to the displacement of the object from its mean or initial position. If an object is in motion such that the acceleration of the object is directly proportional to its displacement (which helps the moving object return to its resting position) then the object is said to undergo a simple harmonic motion. An object undergoing SHM always moves like a wave.
