Forms of Energy and Energy Transformation Notes

Forms of Energy 1. All energy falls into two categories: Potential: stored energy and energy of position Kinetic: motion of waves, electrons, atoms, molecules and substances.

2. What Forms of Energy Are There? POTENTIAL KINETIC Chemical Energy Nuclear Energy Gravitational Energy Radiant Energy Electrical Energy Mechanical Sound Thermal Energy

How will we ever remember these?! Just remember the sentence: Cam Newton got really excited making stinky tacos.

Cam= Chemical Newton= Nuclear Got= Gravitational Really= Radiant Excited= Electrical Making= Mechanical Stinky= Sound Tacos= Thermal

1. Cam=Chemical Energy stored in the bonds of atoms and molecules. Example: Matches, chemicals Digestion, batteries

2. Newton= Nuclear Energy stored in the nucleus of an atom. The energy that holds the nucleus together. Example: Breaking down Uranium

3. Got= Gravitational Energy of place or position. Higher=more gravitational energy. Example: two plants at different heights

4. Really= Radiant Example: Visible Light Electromagnetic energy that travels in waves like light.

5. Excited= Electrical Movement of electrons. Example: lamp, computer

6. Making= Mechanical The movement of a substance from one place to another. Motion. Example: Riding a bike, wind

7. Stinky = Sound Movement of energy through substances in waves. Example: bell

8. Tacos= Thermal The vibration or movement of atoms and molecules. Heat. Example: heat from a stove

Law of Conservation of Energy Energy cannot be created or destroyed. Energy can only be transformed (change forms). Energy Transformation When energy changes from one form to another Example: Digestion – chemical  mechanical  thermal Flashlight – chemical  electrical  radiant Playing the guitar – mechanical  sound
