Friction occurs when two objects are in close contact. As speed increases, the two touching objects will be rubbing their particles faster against each other, causing an increase in friction.
The faster you go, the more air you have bashing into your surface. Imagine the molecules comprising air were the size of basket-balls. at walking speed, you'd only have 5 or 6 basket balls hitting you in the face every minute or so and they'd only hit you at walking pace. When you move up to running speed, you suddenly have 15 or so basket balls hitting you in the face every minute at running pace. Riding on a bicycle, you have between 30 and 40 basket balls hitting you in the face every minute at a very high speed. So the faster you go, the more basket balls you have hitting you at a higher speed. These two factors multiply together to give the friction force which increases as a square factor of your speed, (i.e. increase speed by 2, you have 2x the basketballs hitting you 2x as fast which equals 2x2 = 4 times the friction force). I hope this explanation is adequate. Cheers. by Umar siab:)
Brakes work using particles by converting the kinetic energy of the moving vehicle into thermal energy through friction between the brake pads and the rotors or drums. When the brakes are applied, the particles in the brake pads create friction against the rotating surface, causing the vehicle to slow down or stop. The more force applied to the brake pedal, the more particles are pressed against the surface, increasing the friction and decelerating the vehicle.
To increase friction, the car goes faster so that the air resistance becomes greater. To decrease friction the car goes slower to decrease the air resistance acting on the car. Hope that helped:)

basically you know when you do like seperation it causes friction which is diagnosed to help.

Using the 5 characteristics of matter. the particles simply speed up, and the atrractive forces weaken. Thus, there are mroe spaces in between and there is less friction between the particles when you pour them.
To amplify means to intensify or increase something. Friction is a type of force. Consider using a rolling object. The more the speed of the object increases so does the friction. The friction attempts to slow down the object because of gravity, thus increasing frictional force. A rough surface beneath a rolling object as opposed to a smooth surface can also do the same due to air pockets in holes in the surface.

Substances with a large amount of thermal energy have higher average speeds of particle motion. This is because thermal energy increases the kinetic energy of particles, causing them to move faster. The average speed of particle motion can be quantified using temperature, where higher temperatures correspond to higher average speeds of particles.
To calculate mechanical friction loss in a conveyor system, you can measure the force needed to move the conveyor belt at a constant speed using a dynamometer. By dividing this force by the weight of the load on the conveyor belt, you can calculate the coefficient of friction. Then, you can use this coefficient in conjunction with the belt length, speed, and other factors to determine the mechanical friction loss.
I never heard of friction reducing friction. You can reduce friction by using lubricants, as well as using wheels (as in ball bearings).
