for slowing down, stopping etc
In engines - during ice skating.
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.
Ice skating is because you dont go fast and there is rarely any friction
You need friction to slow down or turn while skiing and ice skating. Auto braking during driving. Walking or the movement of the motor vehicle depends on friction or there will not be movement.

There is not a sport in which friction is not useful. In hockey, for example, there seems to be no need for friction. However, in order to get moving or stand at all, the players rely of the friction between their skates and the ice. The friction between their skates and the ice also creates a thin layer of water while they skate, allowing them to glide over the ice. even chess relies on friction so the pieces do not move off the board.
Ice skating uses friction to make you move smoothly across the ice rink.Friction is in just about all movements.
The absence of friction is useful in situations like ice skating, where low friction allows for smooth gliding. It is also important in space travel, where friction is minimal, enabling spacecraft to move through space without resistance. Additionally, reducing friction in machinery can increase efficiency and reduce wear and tear on components.
Ice skates experience kinetic friction when in contact with the ice. This type of friction occurs when two surfaces are sliding against each other. Kinetic friction helps provide the necessary grip for ice skating.
Let us go for an answer that you may not have thought of shall we? If you were skating on ice and you built up speed then stopped skating, eventually you would stop. Why? because ice has friction though very little. This friction works on the friction on the blades of your skates bringing you to a stop.
Yes, a Zamboni reduces friction on the ice by resurfacing it. The machine applies a thin layer of water to create a smooth surface, which helps reduce friction and improve the ice quality for ice skating or hockey.
When you drive a car and stop it is because of friction you stopped. If there was no friction your car won't stop and will slide. Friction also helps with waking, if there was no friction with every step you take you would slip. Friction lets your foot stay in one spot while you move the other foot. Ice has no friction so it is hard to walk on and hard to brake on (if driving a car.)
