What else can I help you with?
How does friction affect iceskating?
Iceskating works because the pressure exerted by the comparatively narrow surface of the blade melts some of the ice, reducing the friction of solid against solid. This is the same principle that allows glaciers to flow, though of course, ice skaters are much faster.
How does friction act on a wheelbarrow?
Friction between the wheelbarrow wheels and the ground allows the wheelbarrow to move when force is applied. Without friction, the wheels would simply slip and the wheelbarrow wouldn't move forward easily. However, too much friction can make it harder to push the wheelbarrow.
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.
What Is Little In Friction?
In the context of friction, "little" would typically mean that there is not much resistance or opposition between two surfaces in contact. This would result in smoother movement and less energy loss due to friction.
Can static friction be negative?
No, static friction cannot be negative. Static friction always acts in the direction opposite to the applied force and prevents an object from moving when a force is applied. If the external force is removed, static friction drops to zero.
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.
Can static friction be negative?
No, static friction cannot be negative. Static friction always acts in the direction opposite to the applied force and prevents an object from moving when a force is applied. If the external force is removed, static friction drops to zero.
Why it is not wise to reduce friction always?
Well if you did not have friction you would fall over when you walked. Just think of what it is like trying to walk in ice (which has very low friction).
If you push horizontally on your book with a force of 1 N to make the book slide at constant velocity how much is the force of friction on the book?
The force of friction would also be 1 N, equal in magnitude but opposite in direction to the force you are pushing with. This equal and opposite force of friction is what allows the book to move at a constant velocity.
