by experiment.

attach a pulley to the edge of a table.

attach a known weight to a string through the pulley to another known weight on the table-top.

put the particular surface who's coefficient of friction you wish to measure between the table top and the second known weight set on the table top.

allow the first know weight to fall.

measure its rate of descent.

compare its rate of descent with that of the free fall acceleration of gravity for your particular latitude.

you now have all the data you need to figure out the coefficient of kinetic friction.

can you do that yourself or do you need to know more?

A block accelerates at 3.2 down a plane inclined at an angle 30 degrees. Acceleration of gravity is 9.8. Whats the coefficient of static friction between the block and the inclined plane?

Static friction does not apply when the block is already moving. Without friction, the force on the block parallel to the surface of the incline is Fg*sin(angle), so the acceleration without friction is 9.8* sin(30) = 9.8 * (1/2) = 4.9 Since it is accelerating at 3.2, friction is slowing down the block by (4.9-3.2 = 1.7). The coefficient of kinetic friction is (1.7/4.9) = 0.346939


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.


How do you find the minimum coefficient of static friction for a mass on an incline of 32 degrees?

The equation for friction is F=uN. F (friction), u (coefficient of friction), and N (normal). So you first need to solve for the normal by using Newton's second law. Also solve for the x component of the gravity force. Since it is static friction, you know it should be at rest, so that x component force should be the same as the force of friction. Knowing that and the normal, plug it into the equation and solve for u.


How do you find the coefficient of static friction?

Use the formula: FsMAX=μsFN if you want to do it experimentally, get the two different surfaces, and angle one until the object on top starts moving. take the tangent of the angle that starts the objects sliding past one another, and that is your coefficient of static friction.


A box of mass 2 kg is set down on a plane inclined 30 degrees from the horizontal The coefficient of static friction is .5 the coefficient of kinetic friction is 0 What is the speed after 3 second?

the maximum value of limiting friction is = coff. of static fric. * normal force. in this case normal force =mgcosA=17N. the coff=0.5 so the maximum friction=0.5*17=8.5N. but the force acting downward on the incline is mgsinA which is =2*10*0.5=10N. as it has breached the value of friction,the block will move.now kinetic fric. will act.As the coff. of kinetic fric.=0,the surface is as good as a frictionless one.use the laws of kinematics to find the velocity(v=u+at,a=gsinA,t=3,u=0) hence the answer is=15m/s. in reality if there is a coff of static fric,ther ewill be a coff.of kinetic fric. good luck. regards carlitos tevez.

How can one find the acceleration of an object when given the coefficient of kinetic friction?

To find the acceleration of an object when given the coefficient of kinetic friction, you can use the formula: acceleration g (k), where g is the acceleration due to gravity (9.8 m/s2) and k is the coefficient of kinetic friction. This formula helps calculate how fast an object is speeding up or slowing down due to friction.


How to find the coefficient of static friction on an incline?

To find the coefficient of static friction on an incline, you can use the formula: coefficient of static friction tan(angle of incline). Measure the angle of the incline using a protractor, then calculate the tangent of that angle to find the coefficient of static friction.


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.

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.


how to draw graph Experiment to find coefficient of static friction?

To determine the coefficient of static friction, you can conduct an experiment by gradually increasing the angle of an inclined plane until an object on the plane just begins to move. You can measure the angle at which this occurs and use it to calculate the coefficient of static friction using the formula: coefficient of static friction = tan(angle).


What is the function of coefficient of static friction?

This coefficient of static friction is needed to find the frictional force between a body and a surface on which body has to move.

Here R is reaction which equals to the weight of the body
