Web20 apr. 2016 · Friction would only act on something moving to accelerate it in the opposite direction its current velocity (which is a vector, because velocity is speed and direction), so friction, from its perspective, always has a negative displacement it works over, so the work friction does is always negative. WebFigure 10.1. 1: Forces on a block on an inclined plane (fg = force of gravity; fn = normal force; fs = shear force). Mass wasting occurs when a slope fails. A slope fails when it is too steep and unstable for existing materials and conditions. Slope stability is ultimately determined by two principal factors: the slope angle and the strength of ...

Friction is a force - Department of Education and Training

WebStatic friction can be much less intuitive than kinetic friction. For a book at rest on a flat table, where the only other forces are the force of gravity and the normal, the static force of friction is zero. If you then push horizontally with a small force, static friction establishes an equal-and-opposite force that keeps the book at rest. http://science8sc.weebly.com/force-of-friction.html http://huttonscience.weebly.com/uploads/4/8/3/8/4838576/c1l1_gravity_and_friction.doc philips anrufbeantworter
