ΔU = mgΔh
Gravitational Potential Energy - On a planet
Average Angular Velocity (not on sheet)
ω=v/r
W=Fs
Work - Force is parallel to direction of displacement
P=ΔE/Δt
Power (W) = Energy (J) / Time (s)
Δp=FnetΔt
Impulse - Change in objects momentum (Ns)
ac = v^2 / r
Magnitude of Centripetal Acceleration (Toward centre of circle)
Fc = mv^2 / r
Centripetal force
F = GMm / r^2
Newton’s law of universal gravitation (Attractive force between two objects)
r^3 / T^2 = GM / 4π^2
Kepler’s Third Law - Planetary orbits
U = -(GMm / r)
Gravitational potential energy - Regarding planets
dsinθ = mλ
Constructive Wave Interference
dsinθ = (m + 1/2)λ
Destructive Wave Intemperance
nx = c / vx
Refractive INDEX
I = Imax . cos^2 . θ
Malus’ Law - Polarisation
I1 . r1^2 = I2 . r2^2
Inverse Square Law - Intensity
Q=mc∆T & Explanation
Specific Heat Capacity - Heat needed to raise temperature by a unit
Q / t = kAΔT / d
Heat transfer
F = qE
E is electric field strength
V = ΔU / q
Used to find electric potential
F = 1 / 1x10^-10 x q1q2/r^2
Coulomb’s Law - Force between charges
F = qv × B & Name
Force on a charge moving in a magnetic field - Lorentz force
F = ilb
Force on a section of wire moving in a magnetic field
φ = BA
Magnetic Flux
F / l = (μ0 / 2π) . (I1I2 / r)
