Energy What is energy?.  Energy is the ability to do work or cause change.

How do we define Energy? The ability to do work & cause a change. Unit of measurement is the Joule ( J ) Examples of how we use energy: – cars move, bake.

All energy is either POTENTIAL or KINETIC. Potential energy is stored energy, either by an object’s position (gravity) or in chemical bonds. Kinetic energy.

Energy - The Ability To Cause Change -. Kinetic Energy  energy due to motion  Kinetic Energy and Speed  the faster an object moves, the more kinetic.

Turn to the very last page of your composition notebook. Write at the top of the page: Test Reflections Write on the first line: Test 2 Then answer these questions: *Which questions (and learning targets) did I miss? *Why did I miss those questions? (silly mistakes, didn't understand it, need more practice, etc.)

DO NOW MONDAY  List as many types of energy as you can.

WHAT IS ENERGY?  Energy is:  the ability to do work.  the ability to cause things to happen

PROPERTIES OF ENERGY 1. Energy is always conserved- it cannot be created or destroyed. This means the amount of energy in the universe is always CONSTANT.

PROPERTIES OF ENERGY 2. Energy can be transferred or transformed  Transferred (moved) from one object to another- it is still the same form of energy (ex. mechanical to mechanical)  Transformed (changed) into other, different forms (ex. mechanical to thermal)

DIFFERENT FORMS OF ENERGY Kinetic- energy of motionPotential- stored energy  Thermal Heat-due to motion of particles  Light/Solar Radiant (transferred as waves)  Electrical From electrons moving  Sound Transferred as waves  Mechanical Anything that has moving parts  Gravitational Energy an object has due to its height  Chemical Stored in the bonds that hold atoms together  Nuclear Stored in nucleus of atoms

DO NOW TUESDAY  What type of energy does a hair dryer involve?

RUBE GOLDBERG  Rube Goldberg was a very creative man.  He was a cartoonist, an engineer, an inventor, a sculptor, and a writer.  He had a “knack” for designing a very complex path to complete a very simple task.  His designs became known as “Rube Goldbergs”  The path to the completion of a task always contained many transfers and transformations of energy.
