Simple Harmonic Motion Flashcards
1
Q
What is damping? and what happens?
A
Forces oppose the motion of the oscillating body. There is a constant time period. Peak of resonance shifts to the left.
2
Q
What is resonance?
A
Driving frequency is equal to natural frequency, oscillator oscillates at maximum amplitude.
3
Q
What conditions must be satisfied about SHM acceleration?
A
- acceleration is proportional to displacement.
- acceleration is directed towards the equilibrium position.
- acceleration is in the opposite direction of displacement.
4
Q
What is tension equal to in a pendulum?
A
T = 2pi(L/g)^1/2
5
Q
What is tension equal to in a spring? SHM
A
T = 2pi(m/k)^1/2
6
Q
When does a spring have elastic potential energy?
A
When it is compressed or stretched.
