The power went out at my house and all I have to use for a light source is my emergency hand crank generator flashlight! What energy transformations are occurring to make it work?

kinetic energy is transforming to electrical energy

chemical energy is transforming to electrical energy

kinetic energy is transforming to chemical energy

electrical energy is transforming to kinetic energy

The two factors that determine the amount of electrical energy are ___________ and __________.

power source and a closed circuit

power source and type of substance

My cordless power drill will not work unless I have a charged battery in it AND press the button. Why?

The battery is needed to provide chemical energy to convert into electrical energy that then converts to kinetic energy. The button closes the circuit to allow the flow of electrons.

The battery is needed to close the circuit to allow the flow of electrons. The button provides kinetic energy to convert into electrical energy to make the drill spin.

The battery is needed to convert the button’s kinetic energy into chemical energy in the battery. Then, the electrical energy flows through the wires and converts to kinetic energy.

The battery is needed to provide gravitational energy to convert into electrical energy that then converts to chemical energy. The button opens the circuit to allow the flow of electrons.

If you look at the picture of the solar water heater, you should notice two dark rectangles below the water storage tank. These are called the solar collectors. Why are they made of a dark material?

Dark materials absorb more light than light materials

Dark material reflects more light than light materials

Light material reflects more light than dark materials

Light materials absorb more light than dark materials

Which conversion is correct for the solar cooker:

Light energy transformed to thermal energy

Light energy transferred to electrical energy

Light energy transformed to sound energy

Light energy transferred to thermal energy

Which statement DOES NOT tell why some things might stop.

Gravity pulls on the object and makes it stop.

Energy is transformed to a type that does not allow continuation such as SE or TE.

The Power Source runs out (battery).

The switch on the power source is turned off.

Two factors that determine the amount of elastic energy are:

power source and a closed circuit

temperature and type of substance

Which statement about batteries and generators is correct?

A battery transforms CE into ELE, while a generator transforms KE into ELE.

A generator transforms CE into ELE, while a battery transforms KE into ELE.

A battery needs an open circuit, while a generator needs a closed circuit.

A battery needs an closed circuit, while a generator needs an open circuit.

Why does a basketball stop bouncing?

All of the energy has been transferred to the air or ground

The ball needs to be inflated with the proper amount of air

Three of these statements are TRUE about Sound Energy and Light Energy. Which statement is FALSE?

Both can travel through outer space

A student hits a tuning fork with a mallet. A high-pitched sound is produced. Which describes what happened?

Energy transfer from the mallet to the tuning fork to the air molecules.

Energy transformation from the mallet to the tuning fork to the air molecules.

Energy transformation from the KE to TE and then TE to SE.

Energy transfer from the mallet to the air.

As sound is produced from the tuning fork, what happens to the energy in the tuning fork?

It decreases because the SE is transferring to the air.

It decreases because the SE is being transformed to the air.

It increases because sound is being produced.

It increases because the sound is transforming KE to the air.

Why does sound energy explain why some things stop?

SE does not help explain why things stop, only TE can do that.

KE transfers to SE when objects impact, slide, etc. and converts to the surroundings, leaving less total energy for the object to keep going.

When objects impact, slide, etc. they create SE and destroy KE which slows the object down.

KE transforms to SE when objects impact, slide, etc. and transfers to the surroundings, leaving less total energy for the object to keep going.

How does CE explain why some things keep going?

CE converts to other types of energy which then transfer to whatever object was losing energy to the surroundings

CE only converts to KE which makes things keep going because KE is the energy of movement

CE reactions can go on forever so energy is created out of nothing and this makes things keep going

CE reactions do not explain why things keep going because they are just explosions and science experiments
