WebA rightward force is applied to a 10-kg object to move it across a rough surface at constant velocity. The coefficient of friction between the object and the surface is 0.2. Use the … WebIn a situation, the contact force by a rough horizontal surface on a body placed on it has constant magnitude. If the angle between this force and the vertical is decreased, the …
WebFigure 7.3 Work done by a constant force. (a) A person pushes a lawn mower with a constant force. The component of the force parallel to the displacement is the work done, as shown in the equation in the figure. (b) A person holds a briefcase. No work is done because the displacement is zero. WebHence, the force of friction is a prominent example of constant force. 3. Upthrust. Upthrust or buoyant force is the force exerted by a fluid on a body that comes in contact with it. For …
WebThere are different types of friction—kinetic and static. Kinetic friction acts on an object in relative motion, while static friction acts on an object or system at rest relative to each … WebOnce there is motion, friction is less and the coefficient of kinetic friction might be 0.30, so that a force of only fk = μkN = (0.30)(980N) = 290N keeps it moving at a constant speed. If the floor is lubricated, both coefficients are considerably less …
