Summary Section 1 - thank you Paula Prieto
Energy can
change.
Everything
in nature is made of atoms, which contain tiny particles called protons and
electrons. Protons have got a positive change and electrons have got a negative
one.
When there
is a equal number of protons and electrons in a object, we say that those
object is electrically charged.
Electrons
can move and change. It can move from one object to another and they can
change.
There is a
force of attraction between objects that have got opposite electric changes .
There is a
force of repulsion between objects that have got identical energy changes.
We can do
an example of those types of energy with two balloons.
