True or False

Matter can be seen and touched.

Back 14

True

Front 15

True or False

Energy can be seen and touched.

Back 15

False

Front 16

True or False

Energy enables things to move and change.

Back 16

True

Front 17

True or False

Energy takes many forms

Back 17

True

Front 18

True or False

Energy can be created and destroyed.

Back 18

False

Front 19

Energy is the ability to do what?

Back 19

Work

Front 20

The potential energy of an object is based on what?

Back 20

Its position or the arrangement of its parts

Front 21

List types of kinetic energy

Back 21

motion

electricity

light

sound

Front 22

True or False

Energy cannot be created or destroyed but it can change forms

Back 22

True

Front 23

The transfer of energy involves what?

Back 23

A force

Front 24

Thermal energy is the ________ of particles in matter.

Back 24

kinetic energy

Front 25

How is thermal energy different from kinetic energy?

Back 25

Kinetic energy is associated with the large item and thermal energy is associated with small particles within the large item

Front 26

True or False

As an object gets hotter the particles move faster and as it gets colder particles move slower

Back 26

True

Front 27

True or False

Thermal energy of particles in matter is felt as heat.

Back 27

True

Front 28

True or False

Heat moves from cooler objects to warmer objects

Back 28

False

Front 29

True or False

Something with a high temperature, such as hot air, will transfer thermal energy to something with a lower temperature, such as cold air.

Back 29

True

Front 30

True or False

The faster-moving particles in the hot air cause the slower-moving cold air particles to speed up when they come in contact.

Back 30

True

Front 31

True or False

Thermal energy an only be transferred between two objects of different temperatures

Back 31

True

Front 32

In what three ways is thermal energy transferred?

Back 32

1. conduction

2. convection

3. radiation

Front 33

Name some materials that are conductors:

Back 33

- copper

- silver

- gold

Front 34

Name some material that are insulators:

Back 34

- rubber

- cloth

- plastic

- wood

Front 35

True or False

Conductors and insulators are opposites. A good conductor is a poor insulator, and a good insulator is a poor conductor.

Back 35

True

Front 36

What 3 principles act as guides to what the physical universe is like and how it behaves?

Back 36

1. the universe consists of matter and energy, which interact with each other.

2. energy takes many different forms.

3. matter is composed of specific kinds of particles that are arranged in particular ways.
