How can you measure the sliding friction?

Answer 1

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

Answer 2

Yes you can, and here is an example:

This is an experiment for measuring the amounts of sliding friction between an object and a surface using a ramp.

Answer 3

You measure the sliding force and the verical (to a horizontal saurface) force. Yoy divide sliding/vertical and yoy have the sliding friction coefficient.

Answer 4

Rolling friction is greater than sliding friction as-

IT is easier to roll a bag than to slide it.

that is why cars have wheels so that they can move faster.
