Factors that determine the amount of fluid friction on a solid object include the viscosity of the fluid, the surface texture of the solid object and the shape of the object. By changing any of these factors, you can increase or decrease the amount of resistive force of fluid friction.
What are the factors affecting friction between two solid objects?
What are the factors affecting the friction between two solid objects? The friction between two solid objects increases by increasing the speed and the surface area of the moving body, The friction between the solid objects increases between the rough surfaces. Click to see full answer.
How does surface area affect the amount of friction?
For these materials, the amount of friction that occurs can, in fact, be affected by the amount of surface area in contact, although at this point the nature of the molecular attractions involved is poorly understood.
What factors affect the amount of fluid friction?
Factors that determine the amount of fluid friction on a solid object include the viscosity of the fluid, the surface texture of the solid object and the shape of the object. By changing any of these factors, you can increase or decrease the amount of resistive force of fluid friction.
Is friction caused by surface roughness?
At least that is the theory, and in fact, it holds true for the classical type of friction, sometimes known as "normal" friction, which is the result of surface roughness. However, in the last several decades an entirely new class of very smooth, lightweight, synthetic materials have been invented and manufactured for a variety of applications.
What are the factors that affect friction between two solid surfaces Class 8?
Answer: The friction between two solid objects increases by increasing the speed and the surface area of the moving body, The friction between the solid objects increases between the rough surfaces.
What are the factors which affect friction and how?
Nature of the surface : The rough surface has higher coefficient of friction resulting in higher friction and the surface with lower coefficient of friction resulting in less friction.Weight of the object place over other: This is the normal reaction which the surface applies on the object.
What are the main factors on which friction depends?
(1) the material of the bodies in contact. (2) quality of machining of the surface in contact. (3) presence of foreign matter between the surface. (4) area of the surfaces in contact.
Friction between solid surfaces
This is an exploration of which factors affect the force of friction when one surface slides across another and which do not.

How does friction affect the motion of an object?
Friction produces unnecessary heat leading to the wastage of energy. The force of friction acts in the opposite direction of motion , so friction slows down the motion of moving objects. Forest fires are caused due to the friction between tree branches.
What is friction dependent on?
The friction is dependent upon the nature of the surface in contact. If the surface is rough the friction generated for the opposing motion of the object is greater as compared to the smoother surface.
What happens when two rough surfaces come in contact?
And hence two rough surfaces, when come in contact with each other, generate frictional force or an opposing force which sometimes may convert into heat between them. The degree of friction increases when the roughness increases as it is harder to walk on a road with many pebbles and easier to walk on a leveled road.
What is the force that opposes two objects sliding against each other?
Frictional force or opposing force is a force that opposes two objects sliding against each other, and it acts as a contact force like the normal force. While the normal force acts perpendicular to the flat surface, friction acts in a direction which is along the flat surface of an object.
What is frictional force?
Answer: Friction, force that resists the sliding or rolling of one solid object over another. Frictional forces, such as the traction needed to walk without slipping, may be beneficial, but they also present a great measure of opposition to motion.
How to determine the coefficient of friction?
Relative motion between the object and the balance. One of the ways to determine the coefficient of friction between two surfaces is to pull on an object, using a spring scale that is used to measure the weight of the object. If we lay an object on another surface and ...
What does it mean when the coefficient of friction is low?
A low value of the coefficient of friction indicates that the force required to slide the object is less than the force required when the coefficient of friction is high . The force of friction has the following formula:
How does weight affect friction?
The classical view of friction is that it is caused solely by surface irregularities, called "asperities", and that weight correlates directly with the amount of friction that occurs .
What is coefficient of friction?
coefficient of friction: An empirically derived quantity for a pair of surfaces that is equal to the amount of friction measured divided by the weight of the object being moved.
Why is friction important in airplanes?
Friction is vital to the safe landing of airplanes. In this photograph, a test pilot lands on an unplowed runway to see if the plane can come to a stop without skidding off the runway.
What is rolling friction?
Rolling friction is another type of friction, and it is generally much lower than the sliding friction students experimented with in this and the previous lesson. Have students conduct additional research, both in the form of library/internet research and experimental research, to learn about this type of friction.
Does the coefficient of friction between two surfaces reflect the largest peaks and valleys?
No matter how many smaller peaks and valleys exist, the larger force is enough to free up all of them. The coefficient of friction between two surfaces, because it is empirically derived and based on numerous experiments, reflects the largest peaks and valleys typical of the two surfaces involved.
