Look Familiar?

Keep it in mind

The Mystery It is in everything Nothing happens without it We buy it, we sell it, we use it, we waste it,

everything depends on it We can’t create it, we can’t destroy it It can change form, it can go from one thing to

another REMEMBER THIS

We do, however, know how it behaves; therefore, we can predict what will happen because of it

What is it?

Energy

Main Types of Energy Potential

Stored Energy

It has the potential to do something

KineticMoving Energy

It is making things happen

Forms of Energy Chemical

Stored in the bonds of atoms and molecules contained in foods, fuels, and chemicals

Nuclear Stored in the nucleus of an atom Very large amounts of energy can be

released when the nucleus is split apart

Forms of Energy Sound

Energy that we can hear in the form of waves

Radiant or Electromagnetic Energy from waves

Forms of Energy Electrical

Energy contained in electrons flowing through a wire or in the atmosphere

Heat or Thermal Energy contained in particles of matter as

they move

Forms of Energy Gravitational

Energy due to the position above earth

Mechanical Energy stored in objects by tension

contained in a spring or elastic

Who?

Remember?It Can Change Form

Potential energy can change to kinetic energy

Kinetic energy can change to potential energy

Remember?It Can Go From One Form to

Another

Remember?It Can Go From One Form to

Another Can you pick out the energy

transformations? Too easy! Here are some more

What is the Significance?

Law of Conservation of EnergyCan You Come Up With It? Here’s

a Hint!Energy cannot be created or

destroyed, but it can be changed from one form to another

The amount of energy in the universe is the same now as it

ever was and will ever be!Why?

Food for Thought

Does it sound like another law? Which one?
