Superposition of two impulses (Gauss wave)

This following applet is Superposition of two impulses (Gauss wave)
Created by prof Hwang Modified by Ahmed
Original project Superposition of two impulses (Gauss wave)

First, click the checkbox paused to make the simulation paused when two impulses are very close to each other.
Notice that when the sum of two impulses is maximum, the velocity curve is a horizontal line.
This means that all the energy goes to potential energy and kinetic energy is zero.

If you click + checkbox, one of the impulse will be up side down.
And the sum of two impulses becomes a horizontal line.
It appears that those two wave cencel displacement completely, but check out the velocity distribution at that moment.

You can change the velocity and impulse width with slider,too.
