Document Summary

Maximum angle before objects starts to slip. Center of mass location relative to its footprint. Apply newton"s 2nd law for translational and rotational motion. Coefficient of static friction between the ladder and ground. Example: a ladder part ii (continuation of last example) Newton"s 2nd law f f wall = Newton"s 2nd law for rotations f = f wall = s. About the point of contact between the ladder & ground. Weight + wall = 0. Newton"s 2nd law a f = m. Newton"s 2nd law for rotations (about an axis through the center of mass) Weight + friction + normal = 0 f (rsin ) h n 2. Objects move to minimize their potential energy. U gravity = d gravity = . U gravity = g (gravitational potential energy of a solid object) = 0 is minimized --? du gravity = 0 dy. Unstable - if the cm is outside the footprint. Will lower its potential energy by falling.
