Simple Harmonic Motion
Time it takes for one cycle
Period
What provides the restoring force for a spring mass system?
The Spring
Where is the mass of a simple pendulum concentrated?
The bob
Max displacement from equilibrium
Amplitude
How does frequency relate to pitch?
Higher frequency corresponds to higher pitch (and vice versa)
The two examples of simple harmonic motion we went over
Springs and Simple Pendulums
What does the k mean in Hooke's Law
Spring constant
Where in a simple pendulum is there said to be no mass?
The string or rod
Number of cycles per second
Frequency
Sound needs this to propagate
A medium or object
Position or state that the system naturally wants to return to
What does the minus sign in Hooke's Law mean?
Force is in the opposite direction of displacement
What provides the restoring force for a simple pendulum?
Gravity
Type of interference when the peak of one wave meets the peak of another wave
Constructive
Frequencies above audible human range
Ultrasonic
Force that restores a system back to its equilibrium position
Restoring force
When is the KE of a spring mass system the greatest?
When the mass is passing through equilibrium at its fastest speed.
The initial displacement of a simple pendulum must be less than how many degrees?
15 degrees
Wave where particles move perpendicular to the direction of the wave
Transverse
Type of wave where particles move parallel to the direction the of the wave
Longitudinal
When does an object undergoing simple harmonic motion have the most PE
When it is farthest from the equilibrium position
What affects the period of a spring mass system?
Mass (or spring constant)
What affects the period of a simple pendulum?
Length of rod or string
Area of destructive interference
Node
State of matter sound travels fastest in
