Lecture 1: There are 4 fundamental forces in Nature: 1. Gravitational 2. Weak 3. Strong 4. Electromagnetic Electromagnetism is the underlying force behind most observable phenomena Electricity (Lightning, electric current) Magnetism ( Electric Motors, MRI) Radiation (X-rays, Light) Chemistry Electric Charge Electric charges create electric fields Electric fields lead to forces on electric charges Moving electric charges called current create magnetic fields There are two types of charges: Positive and Negative Like charges repel and opposite charges attract Charge is conserved (cannot be created or destroyed) Charge is quantized in units of electron charge e= 1.6 x 10^1Coulombs Solids often have nuclei arranged in a fixed, periodic pattern Electrons can be bound or free When bound it is called an insulator (wood, glass, rubber) When free it is called a conductor ( metal) Qnet= (Np-Ne)e Lecture 2: Newton’s Third Law says: F 1 on 2= -F 2 on 1 Coulomb’s Law gives the force between point charges: It lies along the line connecting the charges Proportional to the magnitude of each charge Inversely proportional to the separation squared 2 F 1 on 2= K*[(q1*q2)/r ] Where K is a constant equal to 8.99 x 10 Nm Principle of Superposition You must consider one pair at a time to figure out the force on a point charge Calculate the force for each using Coulomb’s law Then add all the vectors together
