Forces that can be considered centripetal force

  1. Oct 14, 2015 #1
    Can you help me find the kind of force that can result in a rotation?(the force that can be considered as centripetal force)
    I know that static friction, contact force, tension, gravity can cause rotation, what else?
    can you help me find as many as possible?

    and kinetic friction can't cause rotation right?

    First, centripetal force is a resultant force, not a specific applied force. In a given context, several forces may contribute to it.
    Although I've encountered other views on this, I believe a centripetal force is any net force that results in a change of direction, i.e. a curved path. "Rotation" might be too restrictive. See e.g. Wikipedia and Hyperphysics on the subject. This would certainly include kinetic friction in some contexts. E.g., consider sliding a block in, initially, a horizontal direction across a sloping surface.
