Coupled Pendula

This simulation shows two pendula coupled by a spring which has a small spring constant (weak coupling). For such systems it is characteristic that the oscillation's energy permanently moves from one partial system to the other.

The "Reset" button brings the system to its initial position. You can start or stop and continue the simulation with the other two buttons. If you choose the option "Slow Motion", the movement will be five times slower. It is possible to change the initial positions of the two pendula by using the corresponding textfields. A positive (negative) angle means an elongation to the right (left) side.
