ENERGY
Conservation of energy – energy is neither created nor
destroyed; it just transfers into different forms.
Let us look at two forms of energy: potential energy and
kinetic energy
Let us look at two forms of energy:
potential energy – stored energy
kinetic energy – energy of motion
When the cart is at the top,
it has lots of stored energy
because of gravity.
Let us look at two forms of energy:
potential energy – stored energy
kinetic energy – energy of motion
This moving cart is
representing kinetic
energy.
Rollercoasters are great examples of potential and kinetic
energy being transferred back and forth.
Chemical reactions are an example of potential energy. The
energy is stored in the bonds between the molecules. Once
the chemical reacts with another chemical, it gives off energy.
Springs store energy when compressed (or extended) and
release it in the form of kinetic energy when let go.
Gasoline has stored energy inside the chemical bond. When
ignited, it gives of a tremendous amount of energy which runs
an engine in an automobile.
Food has stored energy for our muscles. This allows our
muscles to move and get stuff done.
