Ice skatingIn any electric motor. The friction causes the motor to heat up and waste energy.
Rubber has more friction than an ice cube. Ice has almost no friction what so ever.
ice skating on ice ,is one friction occurring

No, all matter contains friction and is shown when in contact with other matter. A molecule of ice has friction, though it may take the tiny thing a few years to have any affect upon something.

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.
You don't get the friction you need to accelerate on ice. This is why asphalt is used on roads, tyres can grip on it and the friction will create higher speeds.
Ice skating is because you dont go fast and there is rarely any friction
because it is slippery and because of gravity
Ice skating uses friction to make you move smoothly across the ice rink.Friction is in just about all movements.
The main disadvantage of friction is that energy is required to overcome friction and that energy is effectively wasted. On the other hand, friction enables motion. If there were no friction, it would be like an extreme case of trying to walk on ice or on a very smooth surface with an oil slick on it. You could not get any traction to start moving or, if already moving, it would be impossible to change the magnitude or direction of motion.
Ice has more friction. Ice has hard ridges that would collide with other ridges easier to make more friction. Grass on the other hand doesn't have a lot of ridges and grass is very bendable.
