What is the coefficient of kinetic friction?
2 can be used on the classic rigid object mechanics. Multipling the coefficient of kinetic friction with normal force on the object gives the power of kinetic friction. Therefore, kinetic friction depends only on the properties of the material and the normal force on the object.
It is important to note that the kinetic friction coefficient is the concept of classical mechanics and part of the theory produced from experimental observations. The classic mechanics were largely developed by British physicist Isaac Newton and its contemporaries in the 17th century. The subject deals with the interaction of large objects moving at relatively low speeds. In particular, the classic rigid solid mechanics relate to this coefficient. This sub -discipline of classical mechanics can describe friction resulting from two fixed assessments Agnavzaje and ignore the forces produced by any fluids.
In this domain, the kinetic friction coefficient can provide very accurate predictions. If fluids are to be considered, it must be introduced POle fluid mechanics. If the scale connected are extremely small, quantum mechanics can solve related complications.
The force created by kinetic friction equals the product of two variables. The first is the coefficient of kinetic friction and the second is normal force. Normal force is the force provided by the surface of the object to prevent another object to move through it. In the case of gravity, it is a vertical force from a country that prevents objects to fall down. The strength is always equal to the gravitational weight of the building in contact with the ground; Therefore, the object can remain calm, because gravitations are precisely abolished by normal force.
The Kinetic friction formula does not include the speed or size of the object. This means that the friction force on the sliding object is independent of how quickly it moves. The friction force on the box will be the same, whether it slips on one mile or a kilometer per hour or two. UnderOutnut is not the power of the building in contact with the ground. It will be the same whether the box is flat and wide or tall and thin.
The coefficient of kinetic friction itself is an empirical feature of the materials. This means that it is only which materials make up two contact surfaces. In addition, such coefficients are derived from the experiment rather than theory. The coefficient of kinetic friction is usually marked with the Greek letter MU with the index.
Due to the identical material, the force of kinetic friction depends only on the normal force on the object. In the case of gravity on the Earth's surface, the force will only depend on the matter of the object. The heavier objects have more proportionally more sliding friction than lighter objects.
