Chapter 12 Review Of Energy

Front 1

On what does kinetic energy depend?

Back 1

Speed and mass

Front 2

Our most important energy resource

Back 2

The sun

Front 3

This is a well-defined group of objects that transfer energy between one another.

Back 3

A closed system

Front 4

This it the total kinetic energy of the particles that make up an object.

Back 4

Thermal Energy

Front 5

What happens to a pendulum's energy as it swings downward?

Back 5

It's potential energy is converted into kinetic energy.

Front 6

When you calculate the amount of work done on an object in order to lift it to a given height, what are you calculating?

Back 6

An object's gravitational potential energy

Front 7

This is the energy an object has because of position or shape.

Back 7

Potential energy

Front 8

This is electrical energy produced from falling water.

Back 8

Hydroelectricity

Front 9

This is the result of chemical energy being converted to thermal energy.

Back 9

Heat

Front 10

This energy depends on weight and height.

Back 10

Gravitational Potential Energy

Front 11

This is the total energy of motion and position of an object.

Back 11

Mechanical energy

Front 12

This energy is the result of the heating of the Earth's crust.

Back 12

Geothermal energy

Front 13

What type(s) of energy is/are converted from the potential energy of a roller coaster as it rolls downhill?

Back 13

Thermal energy, sound energy, and kinetic energy

Front 14

What three examples were given of nonrenewable resources that are fossil fuels and super-concentrated forms of the sun's energy?

Back 14

Coal, natural gas, and petroleum

Front 15

What energy conversion occurred in the food we eat?

Back 15

Light energy converted into chemical energy

Front 16

When you're at the top of your jump on a trampoline, is your potential energy at 0 or is it at a maximum level?

Back 16

The potential energy would be at a maximum level.

Front 17

What are the five types of renewable resources mentioned in the text?

Back 17

Wind energy, solar energy, geothermal energy, energy from water, and biomass

Front 18

This is a force that opposes the motion between two surfaces that are touching.

Back 18

Friction

Front 19

This is energy caused by an object's vibrations.

Back 19

Sound energy

Front 20

This is the energy of moving electrons.

Back 20

Electrical energy

Front 21

This process involves splitting the nucleus of an uranium atom into two smaller nuclei, which releases nuclear energy

Back 21

Nuclear fission

Front 22

These are the conversions that happen when you turn on a light bulb.

Back 22

Electrical energy is converted into light energy and thermal energy.

Front 23

This is the ability to do work.

Back 23

Energy

Front 24

This is organic material that is burned to release energy. Examples include plants, wood, and waste.

Back 24

Biomass

Front 25

This is what work and energy are expressed in.

Back 25

Joules

Front 26

This is the energy conversion involved with the process of photosynthesis.

Back 26

Light energy produces new substances with chemical energy.

Front 27

This is what happens when one object does work on another.

Back 27

Energy is transferred between the two objects.

Front 28

This is the type of energy that some energy is always converted into in every energy conversion.

Back 28

Thermal energy

Front 29

This is the form of energy used to cook food in a microwave.

Back 29

Light energy

Front 30

This is where a roller coaster has its greatest potential energy.

Back 30

At the top of the first hill

Front 31

This law states that energy can be neither created nor destroyed.

Back 31

Law of conservation of energy

Front 32

This energy is produced by the vibrations of electrically charged particles.

Back 32

Light energy

Front 33

This energy is usually "stored" in an object.

Back 33

Potential energy

Front 34

This is the energy conversion that is involved with the use of a microphone.

Back 34

Electrical energy is converted into sound energy.
