Change the bottom slider only

1. Change the bottom slider to the same value as omega null (default 3.14) - This is critically damped motion
2. Change the bottom slider to a higher value than omega null (e.g. 5) - This is over damped motion
3. Change the bottom slider to a lower value than omega null (e.g. 2) - This is under damped motion
