Energy Concepts

Front

What happens to energy when objects collide?

Back

Energy can be transferred from one object to another, changing their motion. Some energy is also transferred to the surrounding air, heating it and producing sound.

Front

How can energy be moved from place to place?

Back

Energy can be moved by moving objects, sound, light, or electric currents.

Front

What is the source of energy released from food?

Back

The energy released from food was once energy from the sun, captured by plants during photosynthesis.

Front

How does light transfer energy?

Back

Light transfers energy from place to place.

Front

How can electric currents transfer energy?

Back

Electric currents can transfer energy to produce motion, sound, heat, or light. They may be produced by transforming the energy of motion into electrical energy.

Front

What is an example of energy transfer through sound?

Back

When a bell rings, energy is transferred from the bell to the air as sound waves, which can then be heard by our ears.

Front

How does energy transfer affect temperature?

Back

When energy is transferred to an object, its temperature can increase as the particles move faster.

Front

What role do moving objects play in energy transfer?

Back

Moving objects can transfer energy to other objects by colliding with them, causing changes in motion or shape.
