0625 Physics formula sheet Cheat Sheet (DRAFT) by

0625 IGCSE physics formulas updates every 2 weeks with a new chapter

This is a draft cheat sheet. It is a work in progress and is not finished yet.

Energy

kE = 1/2mv2
F = ∆p/∆t
∆GPE = mg∆h
W = Fd = ∆E
W = Fd
(%) efficiency = (useful energy output) (total energy input) × 100%
(%) efficiency = (useful power output) (total power input) × 100%
P = W / t
P = ∆E/ t
p = F / A
∆p = ρg∆h
T (in K) = θ (in °C) + 273
pV = constant
c = ∆E / m∆θ

Forces

∆p = ρg∆h (liquid pressure)
Pressure = force / area
W = m x g
kE = 1/2mv2
a = v-u / t
R.F = F.F - B.F
R.F or F = m x a
R.F or F = m x a = m x (v-u/t) = mv - mu /t = change in momentum/t
F = ∆ momentum or P/∆t
impulse = R.F or F x ∆t
impulse = change in momentum/ change in time
m1u1+ m2u2 = m1v1+ m2v2 (conse­rvation of momentum)
m1u1 + m2u2 = (m1+m2) x V (when objects stick together)

Thermal physics

kE = 1/2mv2
F = ∆p/∆t
p is inversely propor­tional to V
W = Fd = ∆E
p1v1 = p2v2
c = ∆ E m∆θ
specific heat capacity = change in thermal energy­/mass x change in temper­ature
P = ∆E/ t
p = F / A
∆p = ρg∆h
T (in K) = θ (in °C) + 273
pV = constant
c = ∆E / m∆θ
 

waves

v = f λ
n = sini/sinr
n = 1/ sinc
 

Motion

Density = Mass/ Volume
(constant) S = distance / time
a = v-u / t
D (while accele­rating) = v+u x t
D = area under the graph
W = m x g
R.F/ F = m x a
R.F = F.F - B.F
Moment = force x perpen­dicular distance from the pivot
Pressure = force / area
(Liquid) pressure = Density x g x height
X = =new L - original L
F = k/x
