Explain why friction increases as speed increases using the big idea of particles?

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.

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 happens to the particles in a longitudinal wave as the amplitude increases?
the speed at which the energy travels increases.
Can speed affect friction force?
Actually, friction does depend on velocity. If you stop your car you have to ease up on the brakes as you slow down because friction increases as you slow down. This effect has been observed for objects travelling at bullet velocities. Friction decrease as 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 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.
Why does friction never speed up object?
You may be thinking of drag instead of friction. Friction between the floor and your foot increases your speed.
Why does friction increase as the speed increases?
because the forces creating the friction are rub faster(harder).
What increases as the temperature of a soild obejct rises?
The speed of the movement of its particles increases.
What happens of the speed of the particles if the temperature is increased?
It increases.
What happen to the speed if the particles if the temperature is increased?
It increases.
What happens to the speed of the particles if the temperatures is increased?
It increases.
