PHYSICS 152 Chapter Notes - Chapter 26: Fundamental Interaction, Connecting Rod
Document Summary
The electric force is one of the fundamental forces of nature. Basic ovservations of electrical foces can be done by rubbing plastic rods with wool. A common factor in observation of electrical phenomena is that two objects are rubbed together. We will first develop a model for understanding elecric phenomena in terms of charges and forces. The following experiments will obtain the results: two plastic rods--one suspended, one held. When in close proximity, no activity will be observed: two plastic rods--one suspended, one held. In close proximity, the suspended rod will attempt to move away from the held rod: suspended plastic rod rubbed with wool, held glass rod rubbed with silk. In proximity, the plastic rod will be attracted to the glass rod: further tests conclude that more vigorous rubbing results in more powerful forces, and the strength of the forces is greater with less distance. 1, so we will say that the original objects are neutral.
