Chapter 17 - Simple Harmonic Motion Flashcards
In S.H.M, what is equilibrium?
The position the object started in before any force was applied
In S.H.M, when is velocity at it’s maximum?
equilibrium
In S.H.M, at equilibrium what is the object’s acceleration?
0
In S.H.M, what is an object’s displacement?
The distance from equilibrium
What are the two requirements for S.H.M?
The acceleration of the object is directly proportional to its displacement.
The object’s acceleration acts in the opposite direction to its displacement.
What happens to the total energy in the system during S.H.M? (Ignoring friction)
It remains constant
In S.H.M, When is the object’s potential energy at its maximum?
At the object’s amplitude (maximum displacement)
In S.H.M, what is the object’s kinetic energy at equilibrium?
At its maximum
In S.H.M, what is light damping?
When the amplitude of the object gradually decreases with time, but the period of the oscillations is almost unchanged.
In S.H.M, what is heavy damping?
When the amplitude of the object decreases significantly and the period of the oscillations also increases slightly.
What is resonance?
When the natural frequency of an object is the same as the frequency of the driver, causing the driven object to oscillate.
What is the equation for the maximum velocity of SHM?
wA
What is the equation for the maximum acceleration of SHM?
w^2 x A
