Physics Formulas Flashcards
Formulae for Force x2
F=ma (Force=mass x acceleration) (FMA)
F = Pa x A (Force = Pressure x Area) (FPaA)
Formula for Weight
W = mg (Weight = mass x gravitational force(10) (WMG)
Kinetic Energy Formula (KE or Ek)
1/2 x mv2 (1/2 x mass x velocity2)
Gravitational Potential Energy Formula
GPE or Ep
mgh (mass x gravitational force x height)
Units of Power and Formula
x 2
Watts, 'P = W/t' (PWT) (power = Work/time) 'P = I x V' (PIV) Power (W) = Current (A) x Potential Difference (volts)
Definition of Density + formula
Density is the amount of matter occupied per unit volume.
p = m/V (mVP)
Density = mass/volume
Formula for current
I = Q/t (QIT)
Current (A) = Charge (C) / time (s)
I = V/R (VIR)
current = voltage/resistance
Charge formula
Q = I x t (QIT)
EMF, p.d formula
And what units
V = IR (VIR) Potential difference (volts) = Current (amps) x Resistance (ohms)
Energy Transformed Formulae x3
E🔼 = P x t (Energy transformed = Power x Time) E🔼 = I x V x t (Energy transformed = Current x Potential Diff x time) E🔼 = Work E🔼 = F x D
Formulae for Work x 3
W = F x D (Force in the direction x Distance) (WFD) W = E🔼 (Energy Transformed/transfered) (WE) W = P x t (power x time) (WPt)
Units and Formula for Pressure
Pascals
Pa = F/A (FPaA)
Formula for Speed for a wave
V = λ x f Speed = Wavelength (meters x Frequency (Hz)
Formula for a period
T = 1/f
Formula for Frequency
f = 1/T Freq = 1/Period f = V/λ
