Forces & Fields

### Question 1

Question
A field is [blank_start]an area that exerts a force[blank_end] on [blank_start]an object[blank_end] without making [blank_start]physical[blank_end] contact with it. This is sometimes called "[blank_start]forces acting at a distance[blank_end]".
• an area that exerts a force
• something that's grassy and can be found
• a force that exerts an area
• a push, pull or twist
• an object
• school or government property
• all of Earth
• two objects
• physical
• telekinetic
• mental
• telephonic
• forces acting at a distance
• an oval
• the future
• distance acting on a force

### Question 2

Question
What is gravitational force?
• An attraction between the masses
• An attraction between maces
• An attraction between mashes
• An attraction between masses

### Question 3

Question
What is magnetic force?
• A force that causes plastic poles to repel or attract
• A force that causes magnetic poles to repel or attract
• A force that causes magnets to demagnetise
• A force that causes magnetic polls to repel or attract

### Question 4

Question
What is electrostatic force?
• The force that powers Electro from Spiderman
• A force that causes charged phones to repel
• A force that causes charged objects to repel or attract
• A force that causes charged objects to rapunzel

### Question 5

Question
Forces can be measured in [blank_start]Kilowatts[blank_end]
• Kilowatts (Kw)
• Apples (A)
• Newtons (Nt)
• Isaacs (I)
• Newtons (N)
• Oldtons

### Question 6

Question
Mass is the amount of [blank_start]matter[blank_end] in an object - it is usually measured in [blank_start]kilograms (kg)[blank_end] but can be measured in other units such as [blank_start]grams (g)[blank_end] or tonnes (t).
• matter
• mutter
• mattter
• mather
• kilograms (kg)
• kilotonnes (kt)
• 100grams (cg)
• karograms (kg)
• crams (c)
• grams (g)
• gramms (g)
• grammies (gg)

### Question 7

Question
Which of these is needed to show a vector force? (You can select more than one btw)
• magnetude
• direction
• units
• victor
• one direction
• magnitude

### Question 8

Question
Is weight a force?
• True
• False

### Question 9

Question
What is weight measured in?
• Kilograms
• Newtons
• Oldtons
• Kilometres (Duh)

### Question 10

Question
Friction is a [blank_start]retarded[blank_end] force?
• retarded
• retarding
• stimulating
• cool

### Question 11

Question
What do you need to make a scientifically accurate magnet diagram?
• Arrows pointing from North to South
• Arrows pointing from South to North
• The closeness of the lines indicating a stronger magnetic force
• The closeness of the lines indicating a weaker magnetic force

### Question 12

Question
In a magnet, there are areas called [blank_start]domains[blank_end], each of which behaves like a tiny [blank_start]magnet[blank_end]. In an unmagnetised ferromagnetic substance, the domains point in [blank_start]different[blank_end] directions and [blank_start]cancel[blank_end] one another out. In a magnetised ferromagnetic substance, the domains point in [blank_start]the same[blank_end] direction to create defined poles. To magnetise these domains one can either: Align them by stroking the substance with a permanent magnet OR Use electricity to align them and create [blank_start]and elctromagnet[blank_end]
• domains
• domaynes
• doughmains
• domians
• magnet
• magent
• piece of cake
• different
• the similar
• cancel
• magnify
• the same
• a weird
• an electromagnet
• an electronmagnet

### Question 13

Question
What will happen when a positively charged object goes near another positively charged object?
• repel

### Question 14

Question
What will happen if a negatively charged object goes near another negatively charged object?
• repel

### Question 15

Question
What will happen if two objects of the opposite charge go near each other?
• attract

### Question 16

Question
What will happen if a neutral object is placed near a positively charged object?
• attract

### Question 17

Question
What will happen if a neutral object is placed near a negatively charged object?
• attract

### Question 18

Question
What will happen if two neutral objects are placed near each other?
• repel
• dance
• attract
• do nothing
• repulsion
• have fun
