Oscillations Flashcards
1
Q
What happens when an object is dampened?
A
It does not oscillate
2
Q
When does the maximum resonance occur?
A
When the driving force = natural frequency
3
Q
What happens to energy during simple harmonic motion?
A
Energy is conserved in the system
4
Q
How can energy be lost in simple harmonic motion?
A
When dampening occurs and energy is lost to fictional forces
5
Q
What is an oscillation?
A
A regular repeated motion around a fixed point
6
Q
What is the equation for simple harmonic motion?
A
F = -kx
7
Q
What is the acceleration equation for simple harmonic motion?
A
a = -(angular velocity)^2x
8
Q
How do you work out the period of simple harmonic motion?
A
T = square root(L/G) x 2(Pie)
9
Q
What are the two requirements for simple harmonic motion?
A
- Once displaced from the equilibrium, there must be a restoring force to get it back there
- The restoring force is proportional to the displacement
