Essential Question: What are energy transformations? What is kinetic and potential energy?

ENERGY

Turbine Generators spin to cause copper wire and magnets to create electricity.

Water, wind and steam are what spin a turbine.

Turbine – A machine with blades that spin

Answer the 3

questions in

your

notebook.

LAW OF CONSERVATION OF ENERGY

Energy can be neither created nor destroyed.

Energy can only be transformed from one form to another

Energy is constant

Law of ThermodynamicsTotal amount of energy in the universe is constant. Energy can be neither created nor destroyed, but it can be changed from

one form to another

ENERGY

The ability to do work or create change

Energy can be potential (stored) or kineticPotential (stored) energy: energy that is

stored in some way

Kinetic energy: energy of motion, involves movement of some kind

POTENTIAL ENERGIES

Write the definition (Hint: it is underlined)

Write 1 example

GRAVITATIONAL ENERGY

Energy an object has due to place or position, such as its height above the Earth; a form of potential energy

Rock on the edge of a cliff, water behind a dam.

CHEMICAL ENERGY

Energy stored in the chemical bonds between atoms and molecules

Energy plants store by photosynthesis, any food we eat, coal, oil

NUCLEAR ENERGY

Energy stored in the nucleus of an atom; the energy that holds an atom together; sometimes called atomic energy

Uranium in a nuclear power plant and plutonium in a bomb

MECHANICAL (MOTION) ENERGY

The energy of an object or substance in movement; sometimes just called kinetic energy

Person dancing, car in motion, a thrown ball, flowing water.

ELECTRIC ENERGY

The energy of electrons moving or flowing within a substance

Power lines or home wiring, electricity from a battery

LIGHT ENERGY

Electromagnetic energy that travels in waves; also called radiant energy

Sunlight, the light of a lamp or of a TV, or computer monitor

THERMAL (HEAT) ENERGY

The internal energy of a substance due to random vibration and movement of its atoms and molecules; also called thermalenergy.

Heat from the burner of a stove, charcoal grill, forest fire.

SOUND ENERGY

Energy that moves through substances by compression waves; sound

Any kind of sound from humans, machines, animals, Ipods

ENERGY TRANSFORMATIONS

Review:

Energy can be neither created nor destroyed, but it can be transformed.

Light bulbs convert electric energy to light energy

Movement of our bodies converts chemical energy to kinetic energy

School bell converts electric energy to sound energy

Coal to electricity to light

Natural gas to heat to stove
