SHM Flashcards
What is amplitude?
Maximum displacement of an oscillating object from equilibrium
What are free oscillations?
When amplitude is constant and there are no frictional forces present
Define time period
The time taken for one complete oscillation
Define frequency
The number of oscillations per second
How do you calculate phase difference?
(2πΔt)/T
What is the relationship between time period and frequency?
T = 1/f
How do you calculate the acceleration of an object in SHM?
a = -(2πf)^2x
What are the forces that cause the amplitude of an oscillating object to decrease?
Dissipative forces
What is light damping?
The amplitude of oscillations decreases gradually
What is heavy damping?
The system returns to equilibrium without oscillating
What is critical damping?
The system returns to equilibrium in the least possible time without oscillating
What is natural frequency?
When a system oscillates without a periodic force applied to it.
What is forced oscillation?
When a periodic force is applied to an oscillating system
What is resonance?
When an applied frequency is equal to the natural frequency of an object
