5.3 oscillations

• angular frequency is a measure of an objects angular displacement per unit time
• critical damping is a form of damping that reduces the displacement of an oscillating object to its equilibrium position in the quickest time possible without further oscillation
• damping is the dissipation of energy from an oscillating system. The consequence is that the amplitude of oscillation will decrease. Damping occurs when a force opposes the system motion
• forced oscillations are repeated up and down oscillations at the frequency of a driver. The amplitude of oscillation is small at high frequencies and large at low
• free oscillations are oscillations that are not caused by a driver. An object will naturally oscillate at its natural frequency.
• angular frequency is measure of an objets angular displacement over time
• critical damping is a form of damping that reduces displacement of an oscillating object to its equilibrium, position in the quickest time possible and without further oscillation
• damping is the dissipation of energy from an oscillating system and causes amplitude to decrease. Occurs when a force opposes the system motion
• forced oscillation is an oscillation in which a periodic driver force is applied
• free oscillation is the motion of a mechanical system displaced from its equilibrium position and then allowed to oscillate without any external forces
• isochronous oscillator is an oscillator that has the same period regardless of amplitude.
• natural frequency is the frequency that a system naturally oscillates at when there is no driving force
• overdamping is a type of damping where the system is damped more than required to stop the oscillations
• resonance is the increase in amplitude of a forced oscillation when the driving frequency matches the natural frequency of the oscillating system
• simple harmonic motion is the oscillating motion for which the acceleration of the object is directly proportional to its displacement and is directed towards some fixed point
• underdamping is a type of damping where energy is gradually removed form system and the amplitude of oscillation slowly decreases
• If the motion starts at equilibrium, use sine. If it starts at the maximum or minimum, use cosine.
