Coupled Oscillators
Suppose we have two pendula that are coupled by a spring. What is the resulting motion of this system? - Read this note: cosc.pdf
Play
with these Interactive Physics demos of coupled oscillators. Click
on the masses or spring and use the Properties window to change
starting conditions or the spring constant.
- coup_sym.ip.hqx - shows the coupled oscillators in the symmetric mode -- they start at rest and both are displaced from equilibrium by the same amount in the same direction.
- coup_asym.ip.hqx - shows the oscillators in the asymmetric mode -- they start at rest and both are displaced from equilibrium by the same amount in opposite directions.
- coup_mixed.ip.hqx - shows the oscillators in the mixed mode -- they start at rest and only one of the two is initially displaced.
