Roller coaster example

Since _N_ and _W_ are in opposite directions, _N_ will be greater than
_W._

To discuss what is happening at other points in such examples the Law of
Conservation of Energy [1] is used. For example, assume that the cart is
not powered and is not converting energy to heat and sound. The cart will
be going faster at position than at the top - this is because
gravitational potential energy [2] has been transformed into kinetic
energy. [3] The gain in the kinetic energy is the loss of gravitational
potential energy:
