This applet is a very simple gravity (kinda E and M?) demonstration. The red dots are particles while the wells change from black when they are strongly attractive to yellow when they are strongly repelent. To begin the simulation press the "Start" button. You can change the number of particles by selecting the number you want next to "Particle #". If you want to clear out all the gravity well, click the "Clear Wells" button. If you wish to place a new gravity well, first choose the power of the well with the number selector next to "Well Power" and then hold down the shift key and press anywhere on the applet to place the new well. If you want to have well that moves, hold down the alt key and click on the applet where you want the well to start, then click again where you want the well to end. A well will now move back an forth along the line that you have just placed. You can also choose the length of the tails drawn on the particles with the drop down menu, and you can turn on and off friction with the checkbox marked "Friciton", imagine that! You can Have fun!
