I HATE PHYSICS!!!!!!! WOOOO!!!!!!!!
in physics there is ALWAYS these 3 sections
buuuuuuuuuuut before we get to that let's chant the national anthem of physics (law of conservation of energy)
ENERGY CANNOT BE CREATED NOR DESTROYED, ONLY TRANSFORMED FROM ONE STATE TO ANOTHER
you may now be seated
Mechanics (energy)

please memorise these or you will die
I do want to add that Q (as in Q = mcΔt) is the same as thermal energy (Ethermal)
crying so hard right now i really dont wanna fucking do this and neither do you
decided i dont wanna work so I'M DOING DEFINITIIONS
definitions or something i give up
mass: the amount of matter that is contained within an object. it is the same everywhere. measured in kilograms (kg).
weight: the effect of gravity on the mass of an object. it is a force so it's measured in neutons (N).
work: the transfer of energy that occurs when a force is applied to an object, causing it to move in the direction of the force. measured in joules (J).
power: the rate at which work is done (energy is transferred). measured in watts (W) or joules per second (which is the same as watts, J/s)
Electricity (circuits)
I would rather die than fucking do circuits but GUESSS WHAHHAHATATTATT AAAAAAAAAAAAAAAAAAAAA
it should also be knwon that to calculate total resistance in a parallel circuit you must follow this formula
1/R(total)=1/R1+1/R2+1/R3...+1/Rn
Heat temperature stuff
more shit to memorise (please take a photographic gander)
extra things to add
everything here is pretty much self-explanitory if you've been keeping up in class. i hate physics so i probably won't add any more info here. also i only added the heating and cooling curves because i've never heard of them befroe but it makes sense so like yeeeah.
