How does electrical force differ from gravitational force?

The electrical (actually electromagnetic) force is much much much stronger than the gravitational force (10 followed by 38 zeroes times stronger).



The source of the electrical force is charged (positive and negative) matter only (not neutral matter like neutrons), whereas all matter and energy is a source of gravitational force.



The gravitational force is only attractive, whereas the electrical force can be attractive (unlike charges) or repulsive (like charges i.e. negative-negative or positive-positive)
The biggest difference I can think of is gravitational force attracts (draws objects nearer to the source) but electrical force can attract or repel, depending on the circumstances.
Well electrical force affects only charged molecules whereas gravitational force affects everything.



Only different as far as I know.. biology student :D
