Formulas and Key Relations

Conditions for Floating and Sinking

ma = W - F_B'

a = (W - F_B')/m

F_B' = Vρ_Lg

Body floats if F_B' > W or F_B' = W

Body sinks if F_B' < W

Density and Relative Density

ρ = M/V

R.D. = ρ_s/ρ_w = m_s/m_w

R.D. = W1/(W1 - W2)

R.D. of solid soluble in water = (Weight of solid in air / Loss in weight in liquid) × R.D. of liquid

R.D. of liquid = (W1 - W2)/(W1 - W3)

Principle of Floatation and Applications

v/V = ρ_s/ρ_L

W = Vρ_sg

F_B = vρ_Lg

Iceberg submerged fraction = ρ_ice/ρ_water

Key relations

The formula is ρ = M/V.
