when cricket players make the ball swing 1 side is shined if the left side is shined then it swings in to the right handed bats and the rough hits the floor more friction makes the ball swing as the rough side will grip the pitch therefore keeping the seam straight
Ice skating is because you dont go fast and there is rarely any friction
ice skating
Ice skating uses friction to make you move smoothly across the ice rink.Friction is in just about all movements.
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.
In engines - during ice skating.
for slowing down, stopping etc
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.
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.
The friction experienced by a skateboarder on grass is significantly higher than that on ice due to the rough texture and resistance of the grass surface, which impedes motion. In contrast, ice provides a smoother, more slippery surface with much lower friction, allowing for greater speed and easier gliding. This difference in friction affects the skateboarder's ability to accelerate, maintain speed, and perform tricks. Consequently, while skating on grass requires more effort and control, skating on ice offers a more fluid experience.
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.
Friction is basically everywhere, but if there is a object in front of that it will automatically slow you down. Ex.when you are on an ice skating rink nothing can stop you because there is no friction at all. But when you are on a football field the object (grass) is in front of the friction it would slow you down more than it would when you are on an ice skating rink.
