The diagram shows an oscillating block connected to two identical springs. The frequency of oscillations can be increased substantially byA simple pendulum has a bob of mass m and a light string of length l . The string is replaced by a uniform rod of mass m and of the same length l . The time period of this pendulumWhen a body is suspended from a fixed point by a spring, the angular frequency of its vertical oscillations is ₁ . When a different spring is used, the angular frequency is ₂ . TheAs shown in the figure, a block of mass m is suspended from a support with the help of a system of identical springs. The force constant of each spring is k . Therefore, the frequeA particle performs simple harmonic motion at a frequency f . The frequency at which its kinetic energy varies isA vertical spring of length l₀ and force constant K is stretched by l when a mass m is suspended from its lower end. By pulling the mass down a little the system is left off to oscTwo simple harmonic motions are given by x₁=a t+a t and x₂=a t+ a 3 t The ratio of the amplitudes of the first to the second and the phase difference between them respectively arePosition-time graph of a particle moving in a potential field is shown beside.
