A washing machine's motor spins the drum. Which energy transfer does the motor make?
A hand-cranked flashlight has no battery. When you crank it, the bulb lights. The bulb's energy had to come from somewhere.
In earlier grades you saw that energy changes from one kind to another, and a transfer is named by its start and its end.
Your moving hand has kinetic energy. The crank spins the generator's coil, and the generator drives a current.
The current carries electrical energy to the bulb.
So in the generator, kinetic energy becomes electrical energy.
The motor runs the opposite trade: in a motor, electrical energy becomes kinetic energy.
A sailboat trails a small propeller that spins a generator to charge a battery. Name the energy transfer in the generator.
The moving propeller has kinetic energy.
The generator drives a current, and the current carries electrical energy.
In the generator, kinetic energy becomes electrical energy.
In a dam's generator, falling water spins the coil. Which energy transfer happens in the generator?
A cabin fan runs on that battery. Name the energy transfer in the fan's motor.
The current supplies the motor with electrical energy.
The motor spins the blades, which then have kinetic energy.
In the motor, electrical energy becomes kinetic energy.
In a blender's motor, which energy transfer happens?
Mateo says a generator turns kinetic energy into electrical energy. Is Mateo correct?
A playground merry-go-round spins a generator that lights its own lamp. In the generator, which energy transfer happens?
A camping lantern is lit by pulling a cord that spins its generator. Where does the lamp's electrical energy come from?
Rolling downhill, a toy train's motor runs as a generator and charges a small battery. In the generator, which energy transfer happens?
