1A 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]".
- Aan area that exerts a force
- Bsomething that's grassy and can be found
- Ca force that exerts an area
- Da push, pull or twist
- Ean object
- Fschool or government property
- Gall of Earth
- Htwo objects
- Iphysical
- Jtelekinetic
- Kmental
- Ltelephonic
- Mforces acting at a distance
- Nan oval
- Othe future
- Pdistance acting on a force
2What is gravitational force?
- AAn attraction between the masses
- BAn attraction between maces
- CAn attraction between mashes
- DAn attraction between masses
3What is magnetic force?
- AA force that causes plastic poles to repel or attract
- BA force that causes magnetic poles to repel or attract
- CA force that causes magnets to demagnetise
- DA force that causes magnetic polls to repel or attract
4What is electrostatic force?
- AThe force that powers Electro from Spiderman
- BA force that causes charged phones to repel
- CA force that causes charged objects to repel or attract
- DA force that causes charged objects to rapunzel
5Forces can be measured in [blank_start]Kilowatts[blank_end]
- AKilowatts (Kw)
- BApples (A)
- CNewtons (Nt)
- DIsaacs (I)
- ENewtons (N)
- FOldtons
6Mass 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).
- Amatter
- Bmutter
- Cmattter
- Dmather
- Ekilograms (kg)
- Fkilotonnes (kt)
- G100grams (cg)
- Hkarograms (kg)
- Icrams (c)
- Jgrams (g)
- Kgramms (g)
- Lgrammies (gg)
7Which of these is needed to show a vector force? (You can select more than one btw)
- Amagnetude
- Bdirection
- Cunits
- Dvictor
- Eone direction
- Fmagnitude
8Is weight a force?
- AVerdadeiro
- BFalso
9What is weight measured in?
- AKilograms
- BNewtons
- COldtons
- DKilometres (Duh)
10Friction is a [blank_start]retarded[blank_end] force?
- Aretarded
- Bretarding
- Cstimulating
- Dcool
11What do you need to make a scientifically accurate magnet diagram?
- AArrows pointing from North to South
- BArrows pointing from South to North
- CThe closeness of the lines indicating a stronger magnetic force
- DThe closeness of the lines indicating a weaker magnetic force
12In 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]- Adomains

- Kmagnify
- Lthe same
- Ma weird
- Nan electromagnet
- Oan electronmagnet
