Unit of force is Newtons, N, (kg m s-2), in SI units
Newtons Law of Gravity:
m is mass, measured in kg (SI units). Think of it as the charge for gravity.
G = 6.67 10 11 N m2 kg-2 is Newtons gravitational constant

The analysis of electrical circuits is the rst step toward
understanding their operation. The analysis
Electric Charge Quantization
Experiment done by American physicist Robert Millikan demonstrated that electric

Electric Charge Conservation
The net sum of electric charge is always conserved. So when a charged conducting object
is brought into contact with another conducting object, the charges in the two objects may
redistribute, but the net charge of the combine
