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.

∙ 13y agoThe frictional force between two sliding surfaces is the product of the force between them (the normal force or that at right angles to the two surfaces), and a coefficient which is usually less than one, but can be higher sometimes like with a rubber tire on a dry road. Thus the frictional force should not vary with speed. However the faster the surfaces slide, the higher the rate of work done by the frictional force, so the higher the effects of this which will be shown in the amount of heat generated at the points of sliding.

∙ 14y agoIf we push the block harder and harder, the frictional force will increase, until it reaches a maximum (in this case, 2.5N).
If we push harder still, (say, 2.6N), the block will start to move, because we're now pushing harder than the frictional force.

Friction increases as speed increases using the big idea of particles?
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.
Why does friction increase as the speed increases?
because the forces creating the friction are rub faster(harder).
What increase as the average energy of the motion of the particles of matter increase?
the speed increases
What is the relationship between friction and thermal energy?
When temperature increases, particles in an object speed up, which means an increase in thermal energy. Since the particles are moving more now, the potential energy decreases, therefore kinetic energy increases. Overall, when temp goes up, thermal energy goes up, which leads to an increase in kinetic energy.
When an object is moving faster through a fluid -how does this affect the force of friction?
In a fluid, the force of friction tends to increase when the speed increases. The exact relationship, however, is far from simple.

the speed increases
Does the speed of the particles of the matter increase as the temperature of matter increases?
the speed just increases as more temperature molecules try to get far and thus they start vibrating by harshal satish patil.
When the speed of particles in a gas increases what els increases?
As the speed of the particles in gas increases the heat of gas increases as well.

What happens to a particle in a liquid when heated?
The Particles Vibrate , Causing the liquid to evaporate leaving behind a gas. ! Sophie :)
What happens to the speed of gas when heated?
The speed of the gas particles will increase as they are heated. That is why the pressure in a container increases. The particles are hitting the walls of the container with more force as they are heated.
What increases the reaction rate by increasing particle speed?
An increase in temperature will increase the speed of the particles and cause the particles to both bump into one another more frequently and with more energy thus increasing the reaction rate.
Does the speed increase or decrease with the attraction between particles when changed from liquid to gas?
Yes, the speed increases when a liquid changes to a gas, And the attraction between particles also decreases. :) -Anouymous
