If a sphere is rolling
Web9 aug. 2009 · Just the opposite: If there is no friction between sphere and surface, then the sphere cannot roll. It will just slide. It's static friction providing the torque about the center of mass that causes the sphere to roll. To derive the static friction (as Jeff did), just apply Newton's 2nd law to both translation and rotation. WebFor a solid sphere rolling down Translation K E = 2 1 M v 2 Rotational K E = 2 1 I ω 2 = 2 1 [5 2 M R 2] [R v ] 2 [ As for a sphere I = 5 2 M R 2 ] ∴ Total kinetic energy of rolling is 2 …
