This is a draft cheat sheet. It is a work in progress and is not finished yet.
Electric Charge
Terms |
Induction |
process of heating electrically conductive materials |
Conductors |
materials that allow electrons to move separately from their atomic orbits |
Coulomb |
SI unit of electric chagre |
Dipole |
2 equal and opposite charges |
Electric Charge |
electrically charged particles |
Electrons |
carries the smallest type of negative charge |
Field Lines |
| |
Benjamin Franklin |
named the positive and negative charges |
Fundamental Charge |
1.6 x 10-19 |
Conductor |
allows electricity to flow through it |
Insulator |
electric current does not flow freely |
Coulomb's Law |
F = k (q1q2)/r2 |
(electric force increases as charge increases) |
k = coulomb's constant (8.99 x 109) |
(electric force decreases as distance increases) |
q1 = charge of object 1 |
| |
q2 = charge of object 2 |
| |
r = distance of object 1 and 2 from each other |
Vector Analysis - used when 3 or more objects are involved |
| |
Particle |
Proton |
Electron |

Electric Charge 2
Electrostatic Interaction |
1. Any charged objects can attract a neutral object |
2. Unlike charges attract |
3. Like charges repel |
charges of a particle depends on the sum of its electrical charges |
1 C = 6.242 x 1018 |
| |
Ion |
atom or group of atoms that bears one or more positive or negative charges |
Cation |
more proton, positive ion |
Anion |
more electron, negative ion |
