Question

What is Pure Rolling?

Answer

Pure Rolling - In pure rolling motion, the velocity of point of contact of bodies (one rolls over another) is zero. In pure rolling, no energy dissipation takes place. Therefore, the kinetic energy of the body (K) K = K_Roll + k_Trans = 1/2 Iω² + 1/2 mv² =1/2( I = mr²)ω²
