What It Shows The frequency of oscillation of a torsional pendulum is proportional to the square root of the torsional constant and inversely proportional to the square. Finally, the excitations of a free eld, such as the elec-tromagnetic eld, are described by harmonic oscillators (see Notes 39 and 40).
The object oscillates around the equilibrium position, and the net force on the object is equal to the force provided by the spring. Torsional Pendulum Oscillation of mass on wire in torsional mode of oscillation. For another example, the motion of a charged particle in a uniform magnetic eld, a problem of considerable interest in solid state physics, can be transformed into a harmonic oscillator (see Notes 10). In simple harmonic motion, the acceleration of the system, and therefore the net force, is proportional to the displacement and acts in the opposite direction of the displacement.Ī good example of SHM is an object with mass m attached to a spring on a frictionless surface, as shown in (Figure).
