ALL FORMULAE Flashcards
Ohms Law
V = IR
Charge
current x time
Energy transferred (circuits)
charge x voltage
Power (circuits)
current x voltage
Acceleration with time
change in velocity / time taken
Force
mass x acceleration
pressure x area
wavespeed
frequency x wavelength
Mass
density x volume
Pressure
force / area
energy transferred (work done)
force x distance
gravitational potential energy
weight x height (mass x gravitational field strength x height)
weight
mass(kg) x gravitational field strength
kinetic energy
1/2 x mass x velocity squared
density
mass / volume
pressure in liquid
Height of liquid column (depth) x density x gravitational field strength
energy efficiency
(useful energy input / total energy output) x 100
refractive index
sin (angle of incidence) / sin (angle of refraction)
critical angle
sin (critical angle) = 1 / refractive index
word done
force x distance moved
