PHYSICS - EQUATIONS!

SUVAT (5 equations.)

v = u + at

s = 1/2(u+v)t

s = ut + 1/2at²

s = vt - 1/2at²

v² = u² + 2as

Force

F = p/t

F = ma

Momentum

p = mv

Turning Movements

Moment = Fx

Torque = Fd

pressure

pressure = F/Area

pressure = h|roe|g

Work, energy, power

P = W/t

P = Fv

Springs

F = kx

E = 1/2Fx / 1/2kx²

stress = F/Area

strain = x/length

Young Modulus = stress/strain

Current

I = Anev

Work Done (electricity)

W=VQ W=epsilonQ W = VIt

Resistance

R = pL/A

Power (electricity)

P = IV, P=I²R P= V²/R

Potential Dividing

V out = R2/R1 + R2 x V in

waves and young slit experiment

v = f lamda

f = 1/T

Intensity = Power/Area

wavelength = a x/D

refraction

n = c/v

n1sin1 = n2sin2

sin C = 1/n

quantum physics

E = hf

hf = work function + KE

wavelength = h/p

circular motion

angular velocity = 2pi/T or 2pi x f

linear velocity = angular velocity x radius

centripetal acceleration = v²/r or w²r

centripetal force = mv²/r or mw²r

oscillations

a = -w²x (a maximum is when x = Amplitude)

v = wA (v max is when x = 0)
