Every
object with mass
that can be affected by gravity has
Potential
Energy
PEg
= mgh. If your
derby car is in a position to be affected
by gravity (resting at the start pin),
it has gravitational potential energy.
Once the car is in motion it has velocity
and the Potential
Energy
is converted to Kinetic
Energy
KE
= (1/2)mv2,
which is the energy of motion. There
is a direct relation between gravitational
potential energy and the height
of an object; the higher that an object
raised above the the ground, the greater
the gravitational potential energy.
