Super physics fun time!

Here are some of the key important things that we learned yesterday during our fulfilling 8th period physics class:

-Charges in a system may be transfered from one object to another.

-Objects become electrically positive or negative when they have a deficiency or excess amount of e-.

-The formula Q=ne
q= total charge
n= number of elementary charge
e= elementary charge

Coulombs Law: The electrostatic force between two point charges is:
Directly proportional to product of charges, inversely proportional to square of distance between centers.

Formula: Fe= K(q1q2/r^2)
r= distance between centers of q1 and q2
k= electrostatic constant (k= 8.99 x 10^9 n-m^2/c^2
