Energy Transformations Practice

Describe the energy transformation that is occurring in each sentence. A rotating turbine generates electricity to power a blow-dryer.

• mechanical → electrical → thermal

• thermal → mechanical → electrical

• electrical → thermal → mechanical

• mechanical → thermal → electrical

Describe the energy transformation that is occurring in each sentence. Lion on a cliff’s edge pounces onto a deer below and consumes it.

• gravitational → chemical

• chemical → thermal

• kinetic → potential

• electrical → mechanical

Describe the energy transformation that is occurring in each sentence. Electricity flows to the microwave as it reheats your food and beeps when it is ready.

• electrical → thermal → sound
