Overview of Oscillation Flashcards
The three requirements for periodic oscillatory motion are
equilibrium state
restoring force (potential energy)
inertia (kinetic energy)
This opposes a change in velocity as restoring force returns system to equilibrium…
inertia
Oscillation results from the exchange between _____ and ______
restoring force
inertia
two common properties NOT required for oscillation
damping
external applied force
Forces do ______ as objects move through a _______
Work
Displacement
Work done by a _______ force causes the _______ to change
conservative
potential
When a force does work on an object the _______ energy of the object ________
kinetic
changes
When the work is positive does the kinetic energy increase or decrease?
increase
When the work is negative does the kinetic energy increase or decrease?
decrease
If the shape of the curve is concave down that means it is
unstable equilibrium
If the shape of the curve is concave up that means it is
stable equilibrium
Frequency is independent of the _______ conditions and the ______
initial
amplitude
The principal of _________ is a complicated periodic oscillation that may be decomposed or built up from a sum of simple oscillations
superposition
