Many upper level tests require pupils to interpret written descriptions of scientific principles. Scholars practice the skill by working through three levels of difficulty. Each question covers kinetic energy, gravitational potential...

Where does the energy of an arrow come from? Is it from the person, the bow, or somewhere else? A simulation allows scholars to adjust the stretch distance and the elastic constant in order to understand where the energy comes from, what...

Hang various mass weights on spring scales while you adjust the spring stiffness and damping in this online activity. Slow down the action, take it to another planet, or watch the amount of potential, thermal, and kinetic energy.

This lab is designed to have students investigate the transformations that occur when elastic potential energy is converted to kinetic energy. Students will be able to modify the mass of the object, the spring constant of the spring and...
