Energy Assessment

Question 1

Elastic

Answer 1

Anything stretched or compressed has elastic energy

Is potential

Question 2

Gravitational

Answer 2

Anything that is above the ground has potential energy
Increased height = more energy
Increased mass = more energy

Question 3

Chemical

Answer 3

Anything with energy stored in it

Energy released with chemical reaction

Question 4

Nuclear

Answer 4

Energy that’s is stored inside the nucleus of the atom

Question 5

Kinetic (motion)

Answer 5

Anything that moves has kinetic energy

Higher velocity = greater energy

Question 6

Thermal (heat)

Answer 6

Everything has some heat energy. The hotter something is the more thermal energy it has.

Question 7

Light

Answer 7

Anything luminous

Question 8

Sound

Answer 8

Anything noisy gives off sound energy the more noise, the more sound energy.

Question 9

Electrical

Answer 9

Where ever there is a current (electrons) flowing, there is electrical energy (electricity)

Question 10

Law of conservation

Answer 10

Energy cannot be destroyed or created but transferred and transformed.

Question 11

Efficiency

Answer 11

Measure of ability to provide useful energy

Question 12

Conduction

Answer 12

When whole object warms up

Question 13

Insulators

Answer 13

Materials that aren’t good conductors

Question 14

Convection

Answer 14

How liquids and gases heat up

Question 15

Radiation

Answer 15

No particle movement involved
Heat transfer is quicker than convection or conduction
Example: suns heat

Question 16

Temperature

Answer 16

Measures how cold or hot something is

Question 17

Heat

Answer 17

Total amount of thermal energy in an object

Measured in Joules

Question 18

Transmitted radiant heat

Answer 18

Clear objects allow heat through

Question 19

Absorbed heat transfer

Answer 19

Dark coloured objects usually absorb light and radiant heat.
Temp increases quickly

Question 20

Reflected radiant heat

Answer 20

Shiny objects/surfaces reflect light/radiant heat.

Question 21

Bioluminescent

Answer 21

Creates light without heat

Question 22

Transparent

Answer 22

Material that allows light to pass through

Question 23

Translucent

Answer 23

Material that scatter the light when passing through
They transmit light
Images aren’t clearly seen

Question 24

Opaque

Answer 24

Materials that are easier to see
Light cannot pass through it
They absorb and/or reflect light

Question 25

Electromagnetic waves

Answer 25

Visible light
Radio waves
Microwaves
Infrared
Ultraviolet light
X-rays 
Gamma-rays
