Forces of any two materials the force required to overcome sliding fiction is greater than the force to overcome starting friction?
If I understand the question correctly: It is actually ill-posed. The frictions you are refering to are dynamic (sliding) and static (starting). I think you will find that static friction is always harder to over come than dynamic friction, not vice-versa.
How can you measure the sliding friction?
In physics a number known as the 'coefficient of friction' is used to calculate the frictional force between any two surfaces. Ff=µFn, Meaning that the frictional force (Ff) is equal to the coefficient of friction (µ) multiplied by the normal force (Fn). If one wishes to calculate the coefficient of friction for two objects, you can pull an object of whatever material you wish along a floor of whatever material you wish. As long as the object remains at a constant speed, the force which you use to pull the object (which can be measured by a force meter) is equal to the frictional force. Once you find the normal force (to find the normal multiply the mass of the object by the acceleration due to gravity on your part of the world, Fn= mg) you simply divide the frictional force by the normal force and you have the coefficient of friction. or just ask your teacher lol
How to find the friction coefficient in a given system?
To find the friction coefficient in a given system, you can use the formula: Friction coefficient Force of friction / Normal force. The force of friction is the force resisting the motion of an object, and the normal force is the force exerted perpendicular to the surface the object is on. By dividing the force of friction by the normal force, you can calculate the friction coefficient.
How do you find the coefficient of friction in a given scenario?
To find the coefficient of friction in a given scenario, you can divide the force of friction by the normal force acting on an object. The formula is: coefficient of friction force of friction / normal force. This value helps determine how rough or smooth the surfaces are in contact.

How do you use sliding friction in everyday life?
u just find it in a book aroni:D
How do you find the normal force and force of friction of an object on a incline?
To find the normal force on an object on an incline, you can use the component of the object's weight perpendicular to the incline. The force of friction can be calculated using the coefficient of friction between the object and the incline, along with the normal force.
What are the two factors that affect the amount of friction between two objects?
Friction is determined by the formula Friction = μFN or alternatively Friction = μFGcos(θ). Therefore the two factors are: (1) the coefficient of friction that depends on the two particular materials (μ) and (2) the normal force operating on the object that is pressing against a larger surface (FN / μFGcos(θ)). Normal force itself has three components upon which it depends: (a) the mass of the object upon which the force acts, (b) the gravity of the body on which the events take place (usually Earth), and (c) the angle of the surface as it deviates from a straight horizontal surface.
Should one add static friction and kinetic friction together to find the total friction force?
No, static friction and kinetic friction are separate forces that act in different situations. When an object is at rest, static friction opposes the applied force. When the object is in motion, kinetic friction opposes the motion. To find the total friction force, you would just consider the friction force relevant to the situation.
What is the coefficient of sliding friction A horizontal force of 100 newtons is applied to a 25kg sack of potatoes Starting from rest The sack achieves a velocity of 2.0ms in 4 secs full answer plz?
fFirst let us find the acceleration. a = v-u / t u = 0 ; v = 2 and t = 4s So a = 0.5 m/s^2 Hence the force on 25 kg will be 12.5 N But applied force is 100 N. So the sliding frictional force = 100-12.5 = 87.5 N Frictional force = uk R = uk m g Hence coefficient of sliding friction = 87.5 / 25*9.8 = 0.357
Methods to reduce friction?
There are two most widely used methods to reduce friction__Using lubricants.Converting Sliding Friction into Rolling Friction
How do you calculate the friction in a pulley?
To calculate the friction in a pulley, you can use the formula: Friction = µ * N, where µ is the coefficient of friction and N is the normal force acting on the pulley. The coefficient of friction represents how "rough" the surfaces in contact are. By multiplying the coefficient of friction with the normal force, you can determine the amount of friction in the pulley system.
