  28. Define hue:
  29. Define saturation:
  30. Define luminosity:

slope m= (y2−y1) (x2−x1)
Volume V = length l × width w × height h
mass m = density ρ × Volume V
ρ= m V
distance d = velocity ѵ × time t
ѵ= Δd Δt
a= Δѵ Δt
ѵ = at
d = ½at²
d = ½gt²
where g is the acceleration of gravity.
g = 980 cm/s² (cgs)
g = 9.8 m/s² (mks)
Gravitational Potential Energy = mgh
Kinetic Energy = ½mѵ²
momentum p = mѵ Force = Δmomentum
Force = mass × Δѵ Δt
Force = mass × acceleration
efficiency= actual mechanical advantage ideal mechanical advantage
percent error= (experimental value−theoretically expected value) (theoretically expected value)
period τ = 1 ÷ (frequency f ) || velocity ѵ = wavelength λ * frequency f
