In a mass spring system, if oscillating vertically, what is the energy transfer
GPE and Elastic PE to kinetic
What happens when there is light damping on something
Damping forces small
Amplitude gradually decreases
Period remains almost unchanged
What happens when there is heavy damping on an object
Large damping forces
Amplitude decreases significantly
Period also increases slightly
What happens when there is very heavy damping
There would be no oscillatory motion, just moves slowly to equilibrium position
Free oscillation
Allowed to oscillate without any external forces
Forced oscillation
driver force is applied to an oscillator, object vibrates at driving frequency
Resonate
When driving frequency = natural frequency, causes amplitude of oscillations to increase largely
What does damping do to resonance
Damping reduces max amplitude at resonance
