Item NG021003: When a hockey puck that is sliding along a level floor hits a wall, motion energy and elastic energy are involved in an energy transformation while the puck is in contact with the wall.
A student slides a rubber hockey puck along a level floor toward a wall. When the puck hits the wall, it compresses a little bit and then slides back toward the student.
Which of the following types of energy are involved in a transformation while the puck is in contact with the wall?
- Only elastic potential energy
- Only kinetic energy (motion energy)
- Kinetic energy (motion energy) and elastic potential energy
- Kinetic energy (motion energy), elastic potential energy, and gravitational potential energy
