1
Q
what is a conductor?
A
a substance or material that allows electricity to flow through it
2
Q
what is an insulator?
A
They do not let electrons flow very easily from one atom to another.
3
Q
charging by fricton
A
when 2 things RUB on eachother
4
Q
charging by conduction
A
when 2 things TOUCH eachother
5
Q
how does a shock happen
A
when the thing has a POSTIVIE charge and all of the elcetrons from your hand flow to the thing that shocks you really fast causing a shock
6
Q
when distance between charges are increased the force….
A
decreases (the smaller the distance the greater the force)
7
Q
net charge
A
the number of charges when you add them together
8
Q
polarized atoms
A
when its electron cloud has been shifted by a charge so that it is not centered on the nucleus.Ωxc
