In this experiment, students build a paper ramp and use it investigate collisions between marbles. By letting a marble go at different heights you can see how both speed and impact change. By choosing different numbers of marbles you can see how much energy is transferred between the marbles. Throughout the investigation, students relate their findings to the marble’s kinetic and potential energies as well as other types of energy such as heat and sound.
- Energy can be transferred into other types of energy.
- Energy is not destroyed.
- Energy is not created--it must come from somewhere.
- Gravitational potential energy is related to kinetic energy of a falling object.
