the conservation of energy Flashcards
What is the equation for change
thermal energy
E = mc x change in termperature
c is the specific heat capacity of material
mass x termparature change x specific heat capacity
What is the equation for nuclear energy
E = mc^2
c is speed of light
What is the equation for elastic potential energy
1/2 Fe
F is the force
e is the extension of material
whats an example of elastic potential energy
the work done in stretching an elastic material is stored as elastic potential energy
define a closed system
any system which all the energy transfers are accounted for. Energy or matter cannot enter or leave a closed system.
define the principle of conservation of energy
The total energy of a closed system remains constant.
Energy can neither be created nor destroyed, it can only be transferred from one form to another.
