According to parallel axis theorem, the moment of inertia of a section about an axis parallel to the axis through center of gravity (i.e. IP) is given by(where, A = Area of the section, IG = Moment of inertia of the section about an axis passing through its C.G., and h = Distance between C.G. and the parallel axis.)

According to parallel axis theorem, the moment of inertia of a section about an axis parallel to the axis through center of gravity (i.e. IP) is given by(where, A = Area of the section, IG = Moment of inertia of the section about an axis passing through its C.G., and h = Distance between C.G. and the parallel axis.)

IP = IG - Ah2

IP = IG + Ah2

IP = Ah2 / IG

IP = IG / Ah2

IP = IG - Ah2

IP = IG + Ah2

IP = Ah2 / IG

IP = IG / Ah2

The loss of kinetic energy during inelastic impact, is given by (where m1 = Mass of the first body,m2 = Mass of the second body, and u1 and u2 = Velocities of the first and second bodies respectively.)

[m₁ m₂/2(m₁ + m₂)] (u₁ - u₂)²

[m₁ m₂/2(m₁ + m₂)] (u₁² - u₂²)

[2(m₁ + m₂)/m₁ m₂] (u₁² - u₂²)

[2(m₁ + m₂)/m₁ m₂] (u₁ - u₂)²

[m₁ m₂/2(m₁ + m₂)] (u₁ - u₂)²

[m₁ m₂/2(m₁ + m₂)] (u₁² - u₂²)

[2(m₁ + m₂)/m₁ m₂] (u₁² - u₂²)

[2(m₁ + m₂)/m₁ m₂] (u₁ - u₂)²
