Energy: Conservation 9th Grade Science

Changing Forms Energy can be changed from one form to another! Examples: http://www.biology-blog.com/blogs/archives/Plant-science-blog/March-22-2006.html http://biodieselreport.com/2007/04/18/biodiesel-chevy-impala-from-pimp-my-ride/

Conversion HowStuffWorks Videos "Matter and Energy: Energy Conversions“

Mechanical Energy Mechanical energy is the sum of potential and kinetic energy If one form is changed to another, the amount of ME doesn’t change Some energy usually becomes non-useful due to friction HowStuffWorks Videos "Work and Energy: Energy"

The Law! Law of Conservation of Energy Energy in a closed system cannot be created or destroyed Energy in a closed system can change form You cannot create or destroy energy First Law of Thermodynamics
