Electrostatics is studying stationary electric charges or fields. This
is talking about positive and negative charges along with neutral charges. In
this picture a student is rubbing there socks on the ground which is charging
by static friction. If it was in a cold dry environment and the student was to
rub their socks and then touch someone, they would get a static shock. This is
caused because of electrons building up and when they get near a neutral or
positive charge they would want to jump off causing a shock. It doesn’t work
very well in wet environments, the charge depletes quicker in that kind of
environment.
