Lesson 4 - Electric Field and Force

Electricity

Phenomenon that pertains to the flow of charge

Electricity

This motion of the charges can power up a lot of things 

Electrons

charged and can produce electric fields around them 

Electric field

of one electron will be felt by another placed around it 

single source of charge

E=F_e/q₀=k|q|/r²  This equation only gives us the electric field of a _____

Electric Field

indicated by electric field lines, which travel from positive to negative ends

strength

The spaces between the electric field lines describe the _____ of the electric field

vector

Electric field is a ____quantity

resultant

This means that all of the rules in vectors can be applied in solving the total (______) electric field in a point 

F=Eq

In a uniform electric field, a charge will experience an electric force described by the following equation

superposition

The net electric field can be solved using the _________ of electric field 

free-body diagram

Since electric field is a vector quantity, we can always use a _____ as part of our analysis 

Cylindrical Symmetry

If we get the sum of all the y-components of the electric field caused by the individual charges along the line segment be equal to zero 

Cylindrical Symmetry

Symmetry can be helpful in simplifying problems in a uniformly distributed charge source or system of charges
