How does low air pressure in bicycle tires reduce the efficiency of a bicycle?
Flabby tyres produce more friction with the road.Less air pressure creates more surface friction, the less surface friction there is the better. (Example look at the very skinny narrow tyres on road racers as they don't need a lot of surface friction while mountain bikes have thick tyres as they need more friction)
How frictions problems are solved?
Friction is useful when I want to stand up (trying to stand on a frictionless surface is difficult, and dangerous), but more friction is a problem when I am ice skating. Friction with my car tires is useful when I am driving on a road (especially if I want to stay on the road around a curve, or want to speed up or slow down), but more friction on the moving parts of the engine is a problem.
Why do you tend to slip on wet and smooth surfaces?
Smooth surfaces are surfaces that have less contact with things touching them and thus have less friction. Less friction means there are fewer contact points to stop your motion. Think of it like this: you are climbing a tree. You grab the next branch. Which is more likely to hold you in place (stopping your motion down), one finger or four? More contact points, meaning more fingers and more friction, means you it is more difficult for gravity (or any other force) to pull you down. In the same way, more contact points because of more friction, such as sand paper, is held in place more firmly. As for water, it acts as a lubricant which causes less friction by stopping the points of contact from actually touching.
Does the coefficient of sliding friction depend on the kinds of materials in contact?
Absolutely! The determination of any kind of friction, kinetic friction (what you call sliding friction, once an object is in motion) OR static friction (the friction it takes to start motion) is determined by the type of materials used. It really depends on the temporary molecular bonds formed between the molecules of the material. The more bonds can form, the less easily something will move (thus the more friction it has)
What is friction affected by?
Weight and surface affect friction. The more mass an object has more friction that will occur ex:/ It would be harder to slide an elephant across a floor than a hockey puck. This is because the large amount of friction on the elephant would slow it down. The smoother the surface the less friction. ex:/ There will be more friction on a floor of sandpaper than there would be on a floor of ice.

Why does Paris metro use rubber tires?
rubber has good grip on road and more over good control on road and while on rubber tyres it's has less jerk convinent journey.
Does using a rubber mate in the shower produce more friction or less friction?
Using a rubber mat in the shower typically produces more friction compared to a smooth surface. The texture of the rubber mat creates a better grip for your feet, which can help prevent slips and falls in wet conditions.
Cars skid more easily on rainy days?
There is less contact between the tyres of the cars and the road surface on rainy days. The rainwater filling up the grooves of the tyres and the rainwater on the surface of the road prevent the tyres from gripping more tightly to the road surface. In other words, water reduces the friction between the tyres and the road surface.(This is the exact answer! Did a lot of research to come up with this answer!)
Does ice has a higher coefficient of friction than rubber does?
Rubber has more friction than an ice cube. Ice has almost no friction what so ever.

What has more friction metal or rubber?
Rubber generally has more friction than metal because of its softer and more flexible surface. The higher coefficient of friction makes rubber better suited for applications where strong grip or traction is necessary, such as in tire treads or shoe soles. Metal surfaces, on the other hand, tend to be smoother and have lower friction.
Does a rough bumpy surface get more friction or less friction?
more
Will installing bigger tire consume more petrol for my car?
Yes. Bigger tyres=> more friction => more strain on engine=> more fuel used
Why does rubber have lots of friction?
Rubber has lots of friction because it has a high coefficient of friction, meaning that it can grip surfaces effectively. The uneven surface of rubber molecules creates more contact points with other surfaces, resulting in greater friction. Additionally, rubber is elastic and can deform slightly to conform to the surface it is in contact with, increasing the contact area and therefore the friction.
Do seesaw need more friction or less friction?

Does streamlinig produce more friction or less?
