The work-kinetic energy theorem can be applied to the motion of a charged particle in a uniform electric field to relate the particle's displacement to changes in the particle's kinetic energy or speed.

The applet on Page 2 lets you simulate the motion of a charged particle in a uniform electric field. Details on how to use the applet are available under Applet Help on the applet's Help menu.

When experimenting with the applet, open the item "Activities" under Related Items for suggestions on investigations to be carried out with the applet.
