Conservation of Energy
Conservative &
Nonconservative Forces
Conservative
work done by the force on an object moving
from one point to another depends only on
the initial and final positions of the object,
and is independent of the particular path
taken
the net work done by the force on an object
moving around any closed path is zero
Nonconservative
work done depends not only on the starting
and ending points, but also on the path taken

Electrical Energy
Chemical Energy
Energy can be transformed from one form to another, and transferred from one object to another, but the total amount remains constant
The total energy is
neither increased nor
decrease in
any process.
