Document Summary
Physics 8e cutnell and johnson summary of phys1002 content. Chapter 18 electric forces and electric fields. Electric charge is an intrinsic property of protons and electrons: proton carries charge +e, electron carries charge e, where e=1. 60*10-19c, charges are built up (or stripped down) by adding or removing electrons the protons are. Si unit for electric charge is the coulomb (c) i(cid:374) the (cid:374)u(cid:272)leus a(cid:374)d do(cid:374)(cid:859)t (cid:373)o(cid:448)e! Thus elect icty refers to the flow of electrons. 18. 2 charged objects and the electric force. Law of conservation of electric charge during any process, the net electric charge of an isolated system remains constant: opposite charges attract, while same charges repel. If an object loses electrons, it becomes more positive and its mass decreases. If an object gains electrons, it becomes more negative and its mass increases. Su(cid:271)sta(cid:374)(cid:272)es that do(cid:374)(cid:859)t tra(cid:374)s(cid:373)it (cid:272)harge easil(cid:455) = i(cid:374)sulators. Separating the objects again simply lets them return to their original charge distributions!
