You might need as little friction as possible in situations like lubricating machine parts to reduce wear and improve efficiency, minimizing friction between moving components in high-speed vehicles like airplanes or cars to maximize speed, or reducing friction between surfaces in medical devices to prevent tissue damage during surgery.
A little friction can be necessary in situations where you need to slow down or control movement, such as when driving a car or walking on slippery surfaces. It can also be helpful in activities like sports that require traction or grip.
Friction needs to be as high as possible when trying to prevent objects from sliding or when maximizing the grip between two surfaces, for example in car tires on a wet road or shoes on slippery surfaces.
In some cases, reducing friction can be beneficial, such as in machinery to increase efficiency and in sports to improve performance. However, friction also plays a crucial role in providing traction, preventing sliding, and enabling control in various situations. Therefore, balancing the need for friction reduction with maintaining safety and stability is important.
NO!You very much need to increase friction between car tires and the road surface in winter. Accumulated snow and ice can already reduce friction there to the point that stopping and steering the car becomes impossible leading to many severe and occasionally fatal accidents.Vehicle brakes also need as much friction as possible to efficiently stop the vehicle when needed.Sandpaper and other abrasives depend on friction to smooth and clean surfaces.etc.
No, you do not need friction to shine a flashlight. A flashlight works by converting electrical energy into light through the use of a bulb or LED and battery. The light produced does not rely on friction to be emitted.
You need a wooden floor and clothes that have little friction together so you could do moves like mummies. You might also need strong muscles for windmills and flares.

low friction
Friction is considered a force because it acts on an item and causes changes, which is what a force is. Nothing would happen if the item was in an area where friction was not possible or if friction was where an object was not since they need each other to exert external effort.

yes! you need friction for lacrosse so you don't fall
On her feet and hands. That is why they build climbing shoes from sticky rubber. Her belay partner will need friction in their belay device (ATC OR GRI GRI, etc)
than what?
Ectomorph because they need to be as light as possible to put as little strain on the horse they're riding as possible.
You need to see a doctor as soon as possible, they might be tumors.
Wheels going over the land have rolling friction. This friction slows down a vehicle. At low speeds, this is the main reason why a car engine is needed to push a car forward. You may have heard of superconductivity. If a superconductor can be created that will work at room temperature, it will be possible to create a vehicle which will operate on tracks without rolling friction. Once set in motion, it will need very little energy to continue moving.
