  Physics Tip


potential energy
Potential energy is the energy possessed by an object because of its height above the ground. The amount of potential energy possessed by an object depends on its mass and its height. A roller coaster car is initially hauled by a motor and chain system to the top of a tall hill, giving it a large quantity of potential energy.
 

  Physics Quote


It is not uncommon for engineers to accept the reality of phenomena that
are not yet understood, as it is very common for physicists to disbelieve
the reality of phenomena that seem to contradict contemporary beliefs of
physics - H. Bauer
