Formula Sheet — Work, Energy and Power

Important formulas and equations from Work, Energy and Power for NEST Physics.

Formulas — Work, Energy and Power

Work and Scalar Product

W = F⃗ · s⃗ = Fs cos θ
A⃗ · B⃗ = AB cos θ = axbx + ayby + azbz
W = ∫ F(x)dx from xi to xf

Kinetic Energy and Work-Energy Theorem

K = ½mv²
K = p²/2m
Wnet = ΔK = Kf - Ki

Potential Energy and Conservation

V(h) = mgh
F = -dV/dx
E = K + V = constant
V = ½kx²

Vertical Circular Motion

T = mv²/r + mg cos θ
vH = √(gr)
vL = √(5gr)
h = 5r/2
