Chapter 5 - Simple Oscillations Flashcards
When displacement is at its max, velocity is at what
Velocity would be zero
What is the maximum displacement from equilibrium position called?
is called the amplitude of the motion
When displacement is at its max, Acceleration is where?
Acceleration is at its max as well.
What happens when an object is not at its equilibrium point
a net force will act on the object so as to restore the object to the equilibrium point.
What is angular frequency?
Angular Frequency, ๐ = 2๐๐ = 2๐/๐ (5.2)
Frequency relative to period is what?
The reciprocal
What is the equilibrium position
this is the point in their motion where the net force on the object is zero
Who first studied the pendulum? And when?
Galileo Galileo (1564-1642) in around 1602
Who studied conical pendulum in 1666?
Robert Hooke
What does oscillation mean
motion is being repeated
What is newtonโs 2nd law
This relates acceleration, mass, and force.
Who constructed the first pendulum clock
Christian Huygens(1653-1703)
In a simple harmonic oscillator the phase of the displacement is related to the phase of the velocity how?
The velocityโs phase is ฯ/2 ahead that of the displacement.
What is the expresssion for KE or T as an expression of time
It will be equal to (1/2) m ฯ^2 A^2 Sin^2(ฯt+ฯ)
What is hooks law for a spring
F = kx where k is the spring constant and x is the displacement.
