What is the average coefficient of friction for a dry road?
The average coefficient of friction for a dry road is typically around 0.7-0.8. This means that the frictional force between tires and the road surface is 70-80% of the normal force pressing the tires onto the road.
Can the coefficient of static friction be equal to the coefficient of kinetic friction?
No, the coefficient of static friction is typically greater than the coefficient of kinetic friction.
What are two ways that friction is harmful while ridinding a bicycle?
There is friction between the rubber tires and the road or other riding surface.There resistance to the rider moving through the air.The bicycle's chain, pedals, gears, etc all develop frictional forces.
What are two examples of surfaces that would have a high coefficient of friction?
Rough concrete surfaces often have a high coefficient of friction due to the texture and unevenness of the material, providing good grip for walking or driving. Rubber on asphalt surfaces also tends to have a high coefficient of friction, which is why tires made of rubber provide good traction on roads.
What is the coefficient of static friction between the two surfaces when the coefficient of static friction is 0.60?
The coefficient of static friction between two surfaces is 0.60.
What part of a bicycle is a useful friction?
The brakes! And the tires (no friction = no traction).
Is friction increased with inflated tires?
No, when your tire is at the optimum recommended pressure friction is least.- You will notice this most on bicycle tires, when pressure is low, it's harder to pedal. I pump my bicycle tires to 45 psi and have a smooth, fast ride.
Why do bicycle tires generate less friction than car tires?
smaller cross-section of tread in contact with road

How friction influenced the invention of the bicycle?
Tires, grips, pedals and brakes needs to have high friction, while all rotating parts needs to have low friction.
Which is the best example of friction A. Applying brakes on a bicycle to slow downB. Getting wind in a cell to move forwardC. Putting gas in a car to driveD. Falling apples from a tree to the ground?
applying brakes on a bicycle to slow down. that's friction because when you apply the brakes, the tires of the bicycle slide on the road causing friction on the road from your tires to slow you down faster

How many tires does a bicycle with 20 tires have?
A bicycle with 20 tires has 2 tires.

Is coefficient of friction or coefficient of limiting friction are same?
Limiting friction is just the maximum static friction force (if you go over that point static friction becomes kinetic friction).Let f = frictional force,c = coefficient of frictionN = Normal forcefmax = cN = limiting frictionAlthough the term coefficient of limiting friction is not really used, I'd assume it would just be "c" (it's a coefficient after all). So they would be the same.If you meant is coefficient of friction the same as limiting friction, than the answer is no. Coefficient of friction is just the "c" in the equation. Limiting friction however is the product of the coefficient and the normal force.
Why does the temperature inside bicycle tires increase?
Basic physics ! Friction between the tyre and the road creates friction. This heats the trapped air within the tyre.
