Work done on an object or system of objects causes a transformation of energy. Consider the following situation:
Along the horizontal section at the bottom of a tall slide, a child slows to a stop.
This situation can best be described as a transformation of
Potential energy into Chemical energy
Kinetic energy into Dissipated energy (e.g., heat)
Potential energy into Kinetic energy
Chemical energy into Dissipated energy (e.g., heat)
Kinetic energy into Chemical energy
