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)
Do rubber tyres show more friction or less friction?
Rubber will have a high coefficient of friction on most surfaces, but we cannot know whether there is more or less friction unless we have something to compare it to.
As soon as an object starts moving what replaces static friction?
Kinetic Friction replaces Static Friction when an object is in motion.
Why is it easier to pull a box in a wagon than to drag it on the ground?
I have the same question omg I don’t know how to answer
Anti-lock braking systems are very good on wet roadways with less then normal or little friction?
The anti-lock braking system usually reduce the skidding that occurs when tires lock and therefore allows the driver more control during emergency braking. Having the tires on ABS can help a stranded driver to veer away from emergency situations.
Which tires produce less friction?
Narrower tires with harder rubber

When a cars tires are stuck in snow or mud is it better to have more less friction and why?
It is better to have less friction because it will be easier to get out.
What are the benefits of radial tires?
Compared to previous versions of tires, radial tires have less rolling friction or less friction with the road while in motion. The result of this is that the tires are generally quieter when driving on the road than the previous version and also allow for better fuel economy.
What is an example of a wheel and axle that make work easier by reducing friction?
An example of a wheel and axle that reduces friction is a bicycle. The wheels allow the bicycle to roll smoothly over surfaces, significantly decreasing the friction between the tires and the ground compared to dragging. This design enables the rider to travel more efficiently and with less effort, as the rotating wheels minimize resistance. Additionally, the bearings used in the axle further reduce friction, enhancing overall performance.
A student riding a bicycle observes that it moves faster on a smooth road than on a rough road. This happens because the smooth road has?
less friction compared to the rough road. On a smooth surface, the bicycle’s tires can roll more easily without encountering significant resistance, allowing for greater speed. In contrast, a rough road creates more friction and drag, which slows down the bicycle's movement. Thus, the condition of the road directly affects the bicycle's performance and speed.
Using the ideas about friction and deceleration explain using a new tire than badly worn tires?
New tires actually have less friction on dry surface than old, bald tires, but once the old tires hit water, you new tires quickly win.
When a car's tires are stuck in snow or mud is it better to have more or less friction?

How does friction on tires effect the stopping distance of a car?
The more friction, the quicker the vehicle will stop, meaning less stopping distance.
When a vehicle hydroplanes its tires?
When a vehicle hydroplanes, the friction the tires are against is something other than the roadway - typically, it's a layer of water between the tires and the roadway. As the water has much less resistance and friction than asphalt, the tires spin much more freely.
What are the differences between folding bead and wire bead bicycle tires?
Folding bead bicycle tires are lighter and more flexible, making them easier to transport and install. Wire bead tires are more durable and less expensive, but heavier and harder to fold for storage or transport.
What is an example of a non-useful friction?
Racing because friction slows you down but you need to go fast.
