CBSE Class 11 Physics Notes Chapter 14: We shall discover a great deal more in this piece. A basic pendulum, which consists of a particle suspended by a thread in the earth's gravitational field, oscillates as an example of a little oscillation. The chapter also explains damped oscillations. Undamped oscillations may result from a periodic modification in the oscillating system's characteristics in addition to a periodic external push. We call this parametric resonance.

Horizontal spring:
Suppose a block of mass m be placed on a smooth horizontal surface and rigidly connected to a spring of force constant K whose other end is permanently fixed.
Vertical Spring:
When the spring is suspended vertically from a fixed point and carries the block at its other end as shown, the block will oscillate along the vertical line.
Combination of springs:
Springs in series:
