Since friction is a force, you need either a force meter or a ramp to measure it. It would be easier to measure with the force meter, but the ramp is more reliable.
Method 1: Force meter.
- attach a force meter to the object.
- place the object on the horizontal surface you want to test.
- pull the object horizontally until it moves. Keep pulling, while looking at the force meter.
- the sliding friction is the average value of that force as you keep pulling.
Method 2: Ramp
- place your object on the ramp. the ramp should have as its surface the material you want to test.
- raise 1 end of the ramp until the object begins to slide. this is the maximum angle you need.
- Decrease the angle of elevation slightly.
- place the object again on the ramp and nudge it. If it keeps moving, decrease the angle again. Repeat until the object is seen to stop after the nudge.
- Use the equation friction = weight of the object in newtons x tangent of the angle.
- repeat all steps and take an average value.
The greater the coefficient of friction between two surfaces, the greater the resistance to sliding between them. The coefficient of friction is a measure of the amount of friction between two surfaces, with higher values indicating a stronger resistance to sliding.
The angle of friction is the angle at which an object on a surface is on the verge of sliding. The coefficient of friction is a measure of the resistance to sliding between two surfaces. The tangent of the angle of friction is equal to the coefficient of friction between the surfaces.

Yes. Sliding friction is also known as kinetic friction.

higher
there is more surface area contact with kinetic friction as opposed to sliding friction
Sliding friction requires more force to overcome its friction.
