Physics - The study of matter and how it affects other matter
In this unit we start with the effects of "static" (that is "not
moving")
electricity. We will look at the causes and the forces produced
by
static electricity. Since in "real life" static electricity
rarely
acts only at a point we will also begin to consider "Force Fields" in
this
case the electric field. A force field is an "invisible
something"
that causes changes in motion (produces forces on other objects).
We
will begin with Coloumb's Law and later see how it is very similar to
Newton's
Law of Gravity and the law for magnetism. Since static
electricity
can cause changes in motion we will also consider the these effects on
a
subatomic as well as large scale (work, electric potential difference,
charge
storage and capacitance).
