Paper 2: Equation
'2 = Squared
Work Done
E = F x D
Work Done (J) = Force (N) x Distance (m)
Kinetic Energy
KE = 1/2 x m x V'2
Kinetic Energy (J) = 1/2 x Mass (kg) x Velocity'2 (m/l)
Power
P = E/t
Power (w) = Energy Transferred (J) / Time (s)
P = V x I
Power (w) = Potential Difference (V) x Current (A)
P = I'2 x R
Power = Current'2 (A) x Resistance (Ohms)
Efficiency
= Useful Power Out / Total Power In
Energy
E = Q x V
Energy (J) = Charge (C) x Potential Difference (V)
Potential Difference
V = I x R
Potential Difference (V) = Current (A) x Resistance (Ohms)
Charge
Q = I x t
Charge (C) = Current (A) x Time (S)
Magnetic Flux Density
F = B x I x L
Force (N) = Magnetic Flux Density (T) x Current (A) x Length (m)
Energy
E = M x L
Energy (J) = Mass (kg) x Latent Heat (J/kg)
Pressure
P = V x Constant...(given)
Pressure (Pa) = Volume (m'3)
P1 x V1 = P2 x V2
Pressure 1 (Pa) x Volume 1 (m'3) = Pressure 2 (Pa) x Volume 2 (m'3)
P = H x p x G
Pressure (Pa) = Height (m) x Density (kg/m'3) x GFS
P = F/A
Pressure (Pa) = Force (N) / Area (m'2)
Force
F = K x e
Force (N) = Spring Constant (N/m) x Extension (m)
Moment
EPe = 1/2 x R x e'2
Elastic Potential (J) = 1/2 x Spring Constant (N/m) x Extension'2 (m)
Gravitational Potential Energy
|> GPE = M x G x |> h
Change in Gravitational Potential Energy (J) = Mass (kg) x Gravity (10 N/kg) x Change in Height
Density
P = M/V
Density (kg/m'2) = Mass (kg) / Voltage (m'2)
Equations Points
'2 = Squared
'3 = Cubed
|> = Triangle for Change
GFS = Gravitation Field Strength
