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]".
Answer
  • 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?
Answer
  • An attraction between the masses
  • An attraction between maces
  • An attraction between mashes
  • An attraction between masses

Question 3

Question
What is magnetic force?
Answer
  • 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?
Answer
  • 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]
Answer
  • 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).
Answer
  • 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)
Answer
  • magnetude
  • direction
  • units
  • victor
  • one direction
  • magnitude

Question 8

Question
Is weight a force?
Answer
  • True
  • False

Question 9

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

Question 10

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

Question 11

Question
What do you need to make a scientifically accurate magnet diagram?
Answer
  • 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]
Answer
  • domains
  • domaynes
  • doughmains
  • domians
  • magnet
  • magent
  • piece of cake
  • different
  • the similar
  • cancel
  • magnify
  • the same
  • a weird
  • an electromagnet
  • an electronmagnet
