Chapter 2: Energy Study Guide

Vocabulary flashcards based on the 4th Grade Science Study Guide for Chapter 2: Energy.

Energy

The power to make things happen, which can change from one form to another and move from one place to another.

Energy Transfers

The movement of energy from one place to another.

Energy Conversions/Transfer

The process where energy changes from one form to another.

Radiation

A way energy transfers, such as heat from the sun.

Conduction

A way energy transfers by direct contact.

Convection

A way energy transfers by moving air or liquids.

Solar Cell Energy Conversion

What type of energy Changes light energy from the sun into electrical energy.

Heat and motion

A hair dryer converts electrical energy into what type of energy

light energy

A flashlight converts chemical energy from a battery into what type of energy

Electrical into light energy

A lamp converts what type of energy into what different energy (energy in-energy out)

Electrical into motion

A fan converts what type of energy into what different energy (energy in-energy out)

Electrical into heat

A toaster converts what type of energy into what different energy (energy in-energy out)

Electrical into sound

A speaker/radio converts what type of energy into what different energy (energy in-energy out)

Radiation

Heat from the sun is what type of energy transfer

Conduction

What type of energy transfer results from direct contact

Convection

What type of energy transfer results by moving air or liquids

Chemical energy

What type of energy does a battery contain

Light and heat (thermal) energy

The sun produces what types of energy

Motion to heat

Rubbing your hands together create what type of energy that is transferred into a different type of energy

Radiation

What is the main way energy from the sun reaches earth

Electrical to heat

Plugging a space heater into an outlet converts what energy into a different type of energy

No

Can energy be created or destroyed? Yes or no

True

True or false. Energy can not be created or destroyed. Energy can only be transferred (ex: radiation, convection, convention)
