what is the force of friction
Answers
Answer:
here is your answer
Explanation:
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. ... Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.

Answer:
Friction is the force that resists motion when the surface of one object comes in contact with the surface of another. The mechanical advantage of a machine is reduced by friction, or in other words, the ratio of output to input is reduced because of friction. An automobile uses one-quarter of its energy on limiting the friction. Yet, it is also friction in the tires that allows the car to stay on the road and friction in the clutch that makes it possible to drive. From matches to machines to molecular structures, friction is one of the most significant phenomena in the physical world. In this article, let us discuss frictional force and its different types.
A few factors affecting the frictional force:
These forces are mainly affected by the surface texture and amount of force impelling them together.
The angle and position of the object affect the amount of frictional force.
If an object is placed flat against an object, then the frictional force will be equal to the weight of the object.
If an object is pushed against the surface, then the frictional force will be increased and becomes more than the weight of the object.
