1

Energy of motion

Kinetic energy

2

Law of conservation is?

Energy can neither be created or destroyed

3

Change in energy

Energy conversion

4

Blow drier, fan, and stove are a example of?electrical energy is? What is the energy transformation?

The movement of electrons

5

What energy is stored in the__________ compostion of matter? Give examples

Chemical energy that is stored in the chemical compostion of matter
Examples: food, firewood,batteries, fuel

6

Nuclear energy is transformed when? Give an example

Center of atom breaks apart or when the nuclei of 2 atoms join together
Ex :the sun

7

A skier on top of a hill is?

Gravational potential energy

8

Energy conversion means

Enrgy is changing from another

9

Bioling wateris an example of?

Thermal

10

Energyfrom the vibrations of particles in a solid, liquid or gas

Sound

11

Any stored enrgy is?

Potetial

12

Kinetic enrgy is when?

When s Something is moving

13

Nuclear enrgy is

Potential enrgy becuase its stored enrgy and has a potential to be used

14

Gravational enrgy is?

Potential

15

Example of elastic energy is

Spring pressed down

16

How does the law of conservation relate to applying brakes on the bike

Mechanical energy is used to the bicycle, and when the breaks are applied, energy is not lost, but changed into thermal energy due to friction

17

Ball thrown in air at highest point is___________ and as it drops to the ground the pot, energy is converted to____________.

Potential and kinetic

18

Potential energy is stored energy due to?

Its position and chemical compostion

19

Energy is?

The ability to cause motion

20

Energy that causes objects to move

Mechanical energy

21

Examples of mechanical energy is

A moving bicycle, rolling ball, turbines in hoover dam
