2
Conservation of Energy

• Is a physical law which states that energy can be
  converted to a different form, but it is never
  lost all together.

3
Energy Conversion

• States that the total amount of energy in any
  closed system remains constant but can be
  recreated, although it may change forms.

Solar panels are used to capture light energy
from the sun and convert it to electricity.
Green plants undergo photosynthesis to convert
light energy into chemical energy in the form of
food.
4
Energy of Motion

• Is kinetic energy that is causing work.

Energy of Motion
5
Energy of Position

• Is potential energy that is stored in an object.

Energy of Position
6
Energy Transformations

• Is any process of transforming one form
  of energy to another.

7
Kinetic Energy

• Is energy of motion that is causing work.

8
Potential Energy

• Is stored energy or energy of position.
