Simple Harmonic Motion (SHM) is a particular type of oscillation. for constants a 1 and a 2. "Simple harmonic motion" is the term we use to describe the motion of an object where the net force is proportional to the object's displacement from equilibrium. This occurs because the non-conservative damping force removes energy from the system, usually in the form of thermal energy. The time taken for an oscillation to occur is often referred to as the oscillatory period. Damped oscillation The oscillation of a body whose amplitude goes on decreasing with time is defined as damped oscillation. An alternative definition of simple harmonic motion is to define as simple harmonic motion any motion that obeys the differential equation 11. simple harmonic motion • Abbreviated SHM • The position can be described by y = A sin (2πƒt) • A is the amplitude of the motion • The object moves back and forth between the positions y = ± A •. a wave pattern that results when two waves of the same frequency, wavelength, and amplitude travel in opposite directions and interfere.
