Example of where you need friction?
The breaks on your car require friction to make the car stop. Friction between the souls of your shoes and the ground keeps you from sliding.
Do cleats reduce friction?
yes it can also reduce friction especially when its slippery, cleats reduce the surface area that are in contact between the shoes and the ground surface?
Of the two forms of friction which is generally the hardest to overcome?
Friction depends on the roughness of the surface between the objects, it also depends on the area in contact between the objects. Athletes can have spikes on their shoes to maximise friction with the ground.
Why increase friction?
You would increase friction so that you wouldn't slip, by using the brakes on your car of bike you increase friction to stop yourself. Hikers increase friction between their feet and the ground by wearing hiking shoes that grip the ground better. Tires on cars that create more friction make the car go faster, because instead of sliding, the tires grip the ground and push off.
What is wanted friction?
This presumably refers to friction which we find useful. For instance, if you stand on a ladder which is leaning against a wall, it is friction which stops the ladder from slipping. When you walk, friction between your shoes and the ground enables you to push yourself forwards. If the friction is not big enough, you just slip, as on ice.
Does snow increase friction between your shoes and the ground?
Snow decreases the friction between your shoes and ground. That's why cars slide in the winter.
How can you increase the amount of friction between your shoes and the ground?
by increasing the roughness of the ground or increasing the sole of the shoes

Yes

What are the frictional forces while riding a unicycle?
there's friction between saddle and butt, between shoes and pedals, between tire and rim, between tire and ground.

Why are grass courts the fastest type of tennis courts?
because it (the grass) reduces the friction between the ground and your shoes unlike clay courts.

List and Explain 2 reasons why you might increase friction between two objects?
Car tires and the road: increasing friction will allow a car to brake faster. Shoes and the ground: increasing friction will make it less likely for you to slip.
What would happen if there were no friction between the soles of your shoes and the sidewalk?
If there was no friction between the soles of your shoes and the sidewalk, you would be endlessly sliding down it until your momentum stopped you or you ran out of force.
