What is force of friction?
Answers
Explanation:
The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. There are at least two types of friction force - sliding and static friction. Though it is not always the case, the friction force often opposes the motion of an object.

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.
What is Frictional Force?
Frictional force refers to the force generated by two surfaces that contacts and slide against each other.
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.
