Yes, if the friction coefficient is too low, the brakes may not be able to stop the vehicle efficiently, causing them to require excessive pressure to bring the vehicle to a stop. This can lead to poor braking performance, overheating of the brakes, and increased stopping distances, which can be dangerous. It is important to ensure that the friction coefficient is at an optimal level for proper brake function.
The coefficient of static friction is typically greater than the coefficient of kinetic friction because it takes more force to overcome the initial resistance to motion (static friction) than to maintain the motion once it has started (kinetic friction). This is due to microscopic irregularities and interlocking between surfaces when at rest, which require a greater force to break compared to when they are already in motion.
The coefficient of static friction between a wooden bench and a cardboard box may vary depending on the specific materials and surface conditions, but it is typically around 0.4 to 0.6. This means that it would require a force equal to 40-60% of the normal force between the two surfaces to overcome static friction and start the box moving on the bench.
Friction is a force. I'll get back to that.Weight, which is usually measured in pounds or ounces or grams (depending on where you live or what you're measuring), has an official (SI) unit of newtons. An object's weight depends on the gravity affecting that object. (You probably know that you weigh less on the Moon than you do on Earth.)Gravity, which is a force, is consequently measured in newtons, just like weight. All forces are measured in newtons.Therefore, friction, which is a force, is measured in newtons.

No, walking without friction is not possible. Friction is necessary between the foot and the ground to generate the necessary traction for walking and to prevent slipping.

Sliding friction requires more force to overcome its friction.
If you are thinking about driving your car down the road, you require friction between your tires and the road to do so. This is known as kinetic friction, and in classical physics, the equation is as follows:f = mu*Nwhere mu is the coefficient of kinetic friction, N is the normal force (force acting perpendicular to the road by the road), and f is the force of friction acting parallel to the road at the point of contact with your tires.Introduce a thin layer of ice to the road and the coefficient of kinetic friction between your tires and the road drops drastically (mu in the above equation). As a result, your car cannot efficiently convert the force from your engine to a friction force between your tires and the road leading to rotational movement. Depending on the structure of the snow, it will also variably drop the coefficient of kinetic friction.This is why, if you are moving and hit a patch of ice, you may temporarily lose control because your car will be at the mercy of the surroundings and its momentum (or inertia) rather than the steering system (no friction means no response from the steering wheel). Alternatively, if the car is at rest, it will be difficult to start moving.tl;drIce or snow decrease the coefficient of static friction for a surface variably depending on structure. This will decrease the friction force between an object and the surface.
it doesn't require friction but it requires the air to flow in the right way over the wings to make it rise or lower in the sky
Use the formula: FsMAX=μsFN if you want to do it experimentally, get the two different surfaces, and angle one until the object on top starts moving. take the tangent of the angle that starts the objects sliding past one another, and that is your coefficient of static friction.

Rear diff does require friction modifier.
No, walking without friction is not possible. Friction is necessary between the foot and the ground to generate the necessary traction for walking and to prevent slipping.
Ice skating does not require any friction because the skater needs to glide on the ice and if there was any friction on ice the skater would have trouble to skate smoothly on the ice. That is why ice skating does not require any friction at all from my perspective.
