An atom has the same amount of protons and electrons which makes it neutral unless disturbed. when an atom comes in contact with another atom one of them will be come (-) and one will be (+) creating and equal amount of (-)(+) atoms. the one that becomes negative received electrons from the other one, and since the other one now has less electrons then protons it becomes + charged it is a constant chain reaction.
yes it contains both positive and negative
it depends on the charge...if it is positive on a negative they create static if it is positive on a positive or a negative on a negative...nothingAnother view:The friction develops heat.
Friction opposes motion. As long as you define the direction in which the object is moving to be positive, the acceleration due to friction will be negative. If you think about it, you start out with positive speed and friction decreases the speed, so adding friction subtracted from the speed. Note: Friction is counterintuitive when you start dealing with rolling without slipping. This answer doesn't address this.
There is no positive and negative conductor. There are just two ends of a conductor, namely positive and negative. It is usually said that electricity flows from the positive to the negative side of a conductor, but scientists have discovered, that current consists of electrons that always flows from the negative to the positive side.
It becomes static electricity
Friction can be negative or positive depending on the direction in which your measures are positive.
It is positive to negative.
It goes negative to positive.
No electric charges may be positive or negative - electrons have a negative charge; ions have a positive charge.
negative work
In nature there are two types of electricity positive and negative
the reaction of positive enviromental impact of tourism and negative
they are positive and negative noobies
yes it contains both positive and negative
Protons are positive,Electrons are negative
I got chills and there multiplying
