Where friction is useful or nuisance for us?
Lots of friction in the world, some useful, some harmful. But friction is not something that merely exists or does not. It can be measured, and a thing can be said to have too little, too much, or a good amount. If you get a rope burn, when a rope you are holding slips in your hands, that is harmful friction. Friction causes a car to stop when the breaks are put on. An ice skater uses skates because they get traction with their sharp edges, but there is low friction on the blade to slide on the ice. If you were on a roof made of asphalt tiles, and the roof were not too steep, it would be friction that holds you in place. You would know better than to go on the roof if it were covered by ice, because the friction would be too low - it would be slippery.
Can static friction be negative?
No; that doesn't make much sense since it would violate the Law of Conservation of Energy.
How does friction affect the work of a machine?
Well, if, for example, you had interlocking gears, the friction would slow down the speed of how they turn. Friction also causes heat, so too much friction could make a computer or a more advanced machine, melt inside. I think that DEFINETELY affects the work of a machine.
Why it is important for you to reduce friction on compound machine?
Because too much friction can damage the simple machines that make up the compound machine.
Is friction useful when you are on a slide?
if there was no friction on a slide, you would gain speed and slide off and depending on the slide (such as a water slide) kill yourself. too much friction makes it boring.
How much does a sponsored skater make?
around 500,000 a year

Would you slow down or keep moving if there wasn't much friction?
You would keep moving, because friction is what slows you down.
How much money does an ice skater make?
Depends on your age or where u live; probably around $100 & $600.

A 45.0 kg skater is skating at a speed of 12.0 ms The skater coasts to a speed of 6.00 ms How much kinetic energy has the skater lost?
2430
Why do ice skater have outfits?
Ice skater have outfits because when they compet in a competition its much better to wear nice dresses and when you skate it is much easier.

Does friction effect braking force?
Most certainly for without friction the braking system would fail no matter how much force was applied.
How much potential energy does 60 kg skater have at 12 meters above ground?
The skater has potential energy of 7,056 joules.
