Electric Field. A region around a charged object in which an electric force is exerted on another charged object.. Comparing shocks from static electricity and electric currents is like comparing apples and oranges, they are similar but quite different at the same time.. Every year many people are injured and sometimes killed from electrocution as even small amounts of electric current can be lethal. . The next few slides are not on your note. They are just interesting. Electric Fish, Eels, and . Rays. For humans, we know that water and electricity . are . not good to mix. For some animals, this safety concern about electricity is not a problem. In fact, they survive because they can use electricity in the . A . force. is a push or pull exerted on an object.. Energy. is the ability to do work or cause change.. Potential energy . is the stored energy that results from the position or shape of an object.. Electric Potential. QUIZ. Define electric force. What is charge measured in?. If two charges are opposite, what happens to those charges?. 4. The force between two charges can be calculated using the following equation . SPS10.

Comparing shocks from static electricity and electric currents is like comparing apples and oranges, they are similar but quite different at the same time.. Every year many people are injured and sometimes killed from electrocution as even small amounts of electric current can be lethal. . 17.1 . Electric charge and force. Chapter 17: electricity. Electric Charge. Electricity:. force . created by a difference in charges . (+, -) . due to gained or lost electrons. . Protons (+) are trapped in the nucleus, so moving electrons (-) are responsible for electricity. NOTE: I will be plugging grades now, if you have tasks not turned in including projects, please turn them in ASAP before the end of the Second Period today.. . Those who have finished all tasks can move on to today’s tasks..
