WebStatic friction is the force holding an object in place on an incline, such as the cheese in Figure 1. The friction force points against the direction that the object would slide without friction. Static friction keeps gravity from pulling the cheese down the incline. WebYou know the force due to friction is (at most) μ m g, so let's find the force due to deceleration. You know, from kinematics, that v f = v 0 + a t f and x f = x 0 + v 0 t f + 1 2 a t f 2 where x 0, v 0 indicate initial position/velocity, and x f, v f, t f final position, velocity, time. WebStatic friction is a responsive force that increases to be equal and opposite to whatever force is exerted, up to its maximum limit. Once the applied force exceeds f s (max), the object will move. Once an object is moving, the magnitude of kinetic friction fk is given by f k = μ k N. where μ k is the coefficient of kinetic friction. importance of education in nigeria pdf

WebFor an object at rest on a flat table, static friction is zero. If you push horizontally with a small force, static friction establishes an equal and opposite force that keeps the book at rest. As you push harder, the static friction force increases to match the force. Eventually maximum static friction force is exceeded and the book moves. WebFeb 1, 2007 · Sled question.
