Facts about friction physics
WebSolution: On a flat surface, the normal force on an object is N = mg. Using this, we can calculate the force of friction as follows: F = μN F = μ mg Substituting the values in the equation, we get F = (0.400) (40.0 kg) (9.80 m/s 2) F = 156.8 N. The frictional force acting on the boat is 156.8 N. Webviscosity, resistance of a fluid (liquid or gas) to a change in shape, or movement of neighbouring portions relative to one another. Viscosity denotes opposition to flow. The reciprocal of the viscosity is called the fluidity, a measure of the ease of flow. Molasses, for example, has a greater viscosity than water. Because part of a fluid that is forced to …
