Lightning
Can be produced between opposite charges within a cloud, between two or more separate clouds or between the cloud and the ground
Lightning
Clouds become negatively charged, which induce positive charges on the ground
Lightning
Initiates the discharge of lightning
Field Forces
forces that act between objects even if they are not in constant
Electrostatic (Coloumbic) Force
Gravitational Force
Field Forces
Electric Field
Defined as the amount of electric force on a charged body exerted by external charged bodies
Electric Field
Way on how charged communicate to one another
charged particle
produces an electric field around it. Thus, another charged particle reacts to it by experiencing an electric force
charge
produced an electric field in its surroundings, but this electric field cannot exert a net force on the charge that created it
Electric Field
at a point P as the electric force (Fe) acting on a positive test charge (q0) placed at that point per unit charge
vector quantity
Since electric force is a vector quantity, it can already be deduced that electric field is also a____
E= Fe / q0
Formula
Inverse-square Law
still applicable to the electric field equation
directed away
For a positive charge, the field lines should be ____ from the charge
field lines
line around the charge
directed towards
For a negative charge, the field lines will be _____ it
Case 1: Attractive (positive charge and negative charge)
Case 2: Repulsive (positive charges)
Case 3: Repulsive (negative charged)
Drawing Electric Field Lines
Field lines emanate from the positive charge and terminate to the negative charges
Field lines do not intersect at one point. Field lines only meet if the force between the charges is attractive
The density of the lines (number of lines per space), represents the strength of the field
Three Basic Rules in Drawing Electric Field Lines
emanate, terminate
Field lines _____ from the positive charge and _____ to the negative charges
Attractive
Field lines do not intersect at one point. Field lines only meet if the force between the charges is____
strength
The density of the lines represents the ____of the field
density of the lines
number of lines per space
Electrostatic (Coloumbic) Force
calculated using the charges
Gravitational Force
calculated using the mass
higher
higher gravitational forces = ___ mass
Electric Field
Always existing and Only reacts when there is a charge
Electric Field
Force per unit charge
Test charge
will react to it by experiencing electric force
