Describe the energy transformations that occur when you climb to the top of a stairway.
To get to the top of the stairs, work is performed to overcome the opposing force of gravity (energy).
Muscles are being used to climb. Chemical energy is being converted to kinetic energy (energy of motion).
Once at the top of the stairs and you stop, your energy turns into potential energy. The energy is not lost or destroyed, it is stored for later use.
