The diagram above represents a bicyclist at the top of a hill, with four points labeled W, X, Y, and Z.
From point W to point Z, how will this bicyclist tranfer their energy.
The bicyclist will transfer stored energy into energy of motion.
Internal energy will cause the bicyclist to move until the energy is gone and does not exist anymore.
While playing a game at a fair, a person lifts a mallet above her head. She then lets the mallet fall toward a target, as shown below.
Which of the following statements describes an energy change that takes place as the person lifts the mallet and then lets it fall toward the target.
Potential energy is the highest as the mallet strikes the target.
Potential energy converts to kinetic energy as the mallet falls toward the target.
