Theme C - C.1 - Simple Harmonic Motion Flashcards
What is the equilibrium position?
The position an object would rest if all energy is removed from the system.
What are oscillations?
Periodic back and forth motion.
One side of the equilibrium position has _ displacement while the other has _ displacement.
positive, negative3
What is amplitude?
Maximum distance between the crest of a wave and its equilibrium position.
What is the time period?
The time taken to complete one full cycle.
What is frequency?
The rate at which something occurs over a particular period of time or in a given time sample.
What is the formula for time period?
1/f
What is angular frequency?
The angle that an oscillator covers per second.
What is the formula for angular frequency?
ω=2π/f
What is the formula for time period in terms of angular frequency?
T=2π/ω
What is the formula for frequency in terms of angular frequency?
f=ω/2π
What is simple harmonic motion?
Repeated motion around an equilibrium position where the acceleration of the object is proportional to its displacement but in the opposite direction.
What is the formula for acceleration in simple harmonic motion?
a=-(ω^2)x
What is the formula for the time period of a simple pendulum?
T=2π√l/g
What is the formula for the time period of a simple pendulum in a spring mass system?
2π√m/k
