Force x distance = work done
Force x velocity = power
Power out/Power in x 100 = efficiency
Distance/time = speed
Change in displacement/time taken = velocity
Thinking distance + breaking distance = stopping distance

That's pretty much it.

Has anyone got the June 15 paper? I haven't even looked at it yet since I did it last year haha (resisting)

It's crazy how much easier it looks now that we've done A2

Hello, I'm very late to this party but hopefully this should help anyone searching for the same answers who finds this thread.
(Hopefully they're all correct)
-Number density, n = (number of electrons) / (volume)
-Number of molecules = number of moles x NA [Avogadro's: 6.02x10^-23]
-Mass of sample = number of moles x molar mass
-Velocity= (2πr) / T
-Chandrasekhar's limit applied to stars less that 1.44 x (mass of the sun)
- nλ=dsinθ
-Wien's constant = 2.9x10^-3 mKelvin
-1 arc second = (1/3600) degrees
-1 parsec = 3.26 light years
-Hubble's constant = 2.2x10^-18
These are all that I've found for modules 1-3, bearing in mind this is the new spec, as of 2017.

Thanks for the help!
