Web17 aug. 2024 · Kinetic friction is the retarding force experienced by a body when in motion. In other words, it is the minimum force required to keep an object in motion. The requisite for kinetic friction is that the objects should be in relative motion. If the object is in a state of rest then the friction will be called static friction. Web12 sep. 2024 · If two systems are in contact and moving relative to one another, then the friction between them is called kinetic friction. For example, friction slows a hockey …

Web22 dec. 2014 · The general equation for the force of friction (static or kinetic) is F f = μ ∗ F N, where F f is the force of friction and μ is the coefficient of friction (its value is dependent upon the surfaces interacting on each other). WebKinetic Friction If two surfaces are in contact and moving relative to one another, then the friction between them is called kinetic friction. Imagine, for example, trying to slide a … WebThis is the kinetic energy so 1/2mv^2 and you then multiply both sides by 2 and get 16910 = mv^2. The mass is 90kg so divide both sides by 90 and get v^2=187.8889. Square root … cheap playa tambor vacations
