In this document I have explained what static electricity is, and the affects that charged objects have on each other, whether positively charge or negatively charged. I have explain what happens when an object gains or looses electrons, and I have explained and defined what friction is
● An object obtains an electric charge through friction. This charge can either be
positive or negative.
● A charged object has an effect on other charged or neutral objects.
● Objects with different electric charges attract each other. They move closer to each
other.
● Objects with the same electric charge repel each other. They move further apart
from each other.
● A charged object can attract a neutral object. The charges in the neutral object
that are opposite to the charged object are rearranged closest to the charged
object.
● Electrostatic charges are best obtained in dry weather.
REVIEW:
● Objects are usually neutral because they have the same number of positive and
negative charges
● Objects can become negatively or positively charged when friction (rubbing) results
in the transfer of electrons between objects.
● Protons and neutrons cannot be transferred, only electrons can be transferred by
friction.
● If an object has more electrons than protons, then it is negatively charged.
● If an object has fewer electrons than protons, then it is positively charged.
● Like charges repel each other, i.e. negative repels negative; positive repels positive.
● Opposite charges attract each other, i.e. negative attracts positive; positive attracts
negative.
● A discharge of the electrons from a charged object can cause sparks or shocks of
static electricity, especially when the air is dry
