Energy Transformations

Master energy transformations! Fun worksheet on energy types and conservation for 6th grade.

Match each scenario with the energy transformation . a toaster EM to thermal person running chemical to mechanical playing a violin mechanical to sound wind turbine mechanical to EM battery powered radio chemical to sound Nuclear energy is often transformed to _ to make it useful to people. Light Mechanical Electrical Sound When a child swings on a play set, what energy transformation occurs? chemical to light electrical to chemical chemical to nuclear chemical to mechanical When a car's tires spin on the road, friction is generated. In this example, some of the mechanical energy is transformed to _ energy. thermal light nuclear solar Energy cannot be created nor _. found generated destroyed wasted What is a clue to indicate that an object has electromagnetic (EM) energ? it makes a sound it has visible light it is chemically changed It is vibrating rapidly Let's Review! Energy transformation occur when one energy type changes to another. Energy is measured in a unit known as Joules. When an energy transformation occurs there is always some waste, usually in the form of thermal energy or heat. Even though it seems like energy is destroyed or lost the Law of Conservation of Energy tells us that energy cannot be created or destroyed it can only change forms. So when I use 47J of energy to jump rope and then I stop jumping, the closed system still has 47J. The objects in this closed system are me, the jump rope, the ground, and the air.
