Its function is to dampen wind-driven oscillations of the building by oscillating at the same frequency as the building is being driven—the driving force is transferred to the object, which oscillates instead of the entire building.
We begin by studying the type of force that underlies the simplest oscillations and waves. We will then expand our exploration of oscillatory motion and waves to include concepts such as simple harmonic motion, uniform circular motion, and damped harmonic motion.
An oscillation is a back and forth motion of an object between two points of deformation. An oscillation may create a wave, which is a disturbance that propagates from where it was created. The simplest type of oscillations and waves are related to systems that can be described by Hooke’s law.

Oscillating. Examples of simple harmonic motion: -A vertical mass-spring system with no friction -A frictionless pendulum oscillating -A horizontal mass-spring system with no friction
Examples of systems which experience free oscillations are: Simple pendulum - A small, dense bob that hangs from a string, which is attached to a fixed point. Once the bob is displaced and let go, the pendulum will oscillate freely. Mass-spring system - A mass attached to a spring, which will oscillate freely once displaced and released.
12 Μαρ 2024 · You push a child in a swing to get the motion started. The energy of atoms vibrating in a crystal can be increased with heat. You put energy into a guitar string when you pluck it. Some oscillations create waves. A guitar creates sound waves. You can make water waves in a swimming pool by slapping the water with your hand.
