Physics Equation Sheet (E Mich, Lent, Sum)

Physics - Equation Sheet

ρ = (m/V) - density = mass / volume

p = (F/A) - pressure = force / area

Δp = ρgΔh - pressure difference = density x gravitational field strength x height difference

P = (W/t) - power = angry transferred / time taken

P = V x I - electrical power = voltage x current

E = V x I x t - electrical energy transferred = voltage x current x time 

M = F x d - moment = force x perpendicular distance to pivot

v = (2πr / T) - orbital speed = (2π x orbital speed) / time period

Q = I x t - charge = current x time

V = (E/Q) - Voltage = energy / charge

E = I x t x V - give on data sheet in exams

V = I x R - voltage = current x resistance

v = (s/t) - velocity = displacement / time
