Suggested Answer Key
Sound Energy
Sound energy is a combination of both kinetic and potential energy. Sound energy is produced by the vibration of particles. These particles bump into others and these, in turn, move and bump into more. Sound waves can travel as these particles collide. If there are no particles, like in a vacuum, such as space, then the sound cannot travel.
Examples: listening to someone speak, playing a guitar
Magnetic energy
Magnetic energy is the energy exerted by magnets. Magnets create a magnetic field and this field causes the magnets to attract or repel other magnetic objects. Since it was discovered in the 17th century, the number of applications for magnetic energy has been growing continually. Magnetic energy has even been used in the
construction of things like roller coasters, and in machines such as the maglev train, which can travel at hundreds of miles per hour.
Examples: maglev trains, fridge magnets, compasses
