(15 cards)
What is an oscillation?
“An oscillation is a repetitive back-and-forth motion around an equilibrium position.”
What is the difference between periodic and non-periodic motion?
“Periodic motion repeats at regular intervals (e.g.
What is the amplitude of an oscillation?
“The maximum displacement of an object from its equilibrium position.”
What is the phase of an oscillation?
“The fraction of the oscillation cycle that has elapsed
What is the equation for the period of a mass-spring system in simple harmonic motion (SHM)?
“T = 2π√(m/k) where T is the period
What is the equation for the period of a simple pendulum in SHM?
“T = 2π√(L/g) where T is the period
What is damping?
“Damping is the gradual reduction in the amplitude of an oscillation due to energy loss (e.g.
What are the types of damping?
“Light damping (amplitude decreases)
What is resonance?
“Resonance occurs when an external force is applied at the natural frequency of an oscillating system
What is the natural frequency of an oscillating system?
“The frequency at which a system oscillates when disturbed from its equilibrium without external forces applied.”
How does resonance affect an oscillating system?
“At resonance
What is the energy in a damped oscillation?
“In a damped oscillation
What is the relationship between the damping force and velocity?
“The damping force is typically proportional to the velocity of the oscillating object.”
What is the equation for the angular frequency of a simple harmonic oscillator?
“ω = 2πf where ω is angular frequency and f is frequency.”
How does damping affect the phase of an oscillation?
“Damping causes the phase of the oscillation to shift over time
