### Description

A small quiz that highlights all the relevant facts and formulas you need to know about energy transfer.

## Resource summary

### Question 1

Question
The most common forms of energy is c[blank_start]hemical[blank_end] energy, p[blank_start]otential[blank_end] energy, k[blank_start]inetic[blank_end] energy, e[blank_start]lectrical[blank_end] energy and h[blank_start]eat[blank_end] energy.
• hemical
• otential
• inetic
• lectrical
• eat

### Question 2

Question
Not so common forms of energy are l[blank_start]ight[blank_end] energy, e[blank_start]lectromagnetic[blank_end] r[blank_start]adiation[blank_end], s[blank_start]ound[blank_end] and n[blank_start]uclear[blank_end] energy.
• ight
• lectromagnetic
• ound
• uclear

### Question 3

Question
Work is done when a [blank_start]force[blank_end] [blank_start]moves[blank_end].
• force
• moves

### Question 4

Question
work = [blank_start]force[blank_end] x [blank_start]distance moved in a direction of force[blank_end]
• force
• distance moved in direction of force

### Question 5

Question
The unit of work is the [blank_start]joule[blank_end] (J).
• joule

### Question 6

Question
joules = [blank_start]newtons[blank_end] x [blank_start]metres[blank_end]
• newtons
• metres

### Question 7

Question
The work done is a measure of the amount of energy transferred.
• True
• False

### Question 8

Question
power = [blank_start]work done[blank_end]/[blank_start]time taken[blank_end]
• work done
• time taken

### Question 9

Question
The unit of power is the [blank_start]watt[blank_end] (W). 1 W = 1 [blank_start]J[blank_end]/[blank_start]s[blank_end]. 1 kW = 10^[blank_start]3[blank_end] W. 1 mW = 10^[blank_start]6[blank_end] W.
• watt
• J
• s
• 3
• 6

### Question 10

Question
The principle of conservation of energy states: [blank_start]energy[blank_end] cannot be [blank_start]created[blank_end] or [blank_start]destroyed[blank_end]; it is always [blank_start]conserved[blank_end].
• energy
• created
• destroyed
• conserved

### Question 11

Question
efficiency = ([blank_start]useful energy output[blank_end]/[blank_start]total energy input[blank_end]) x [blank_start]100%[blank_end]
• useful energy output
• total energy input
• 100%
