What are two examples of situation where it is best to reduce friction?
It is best to reduce friction in machinery to improve efficiency and reduce wear and tear. Another situation is in sports like ice skating or skiing where reducing friction allows for smoother movement and faster speeds.
What are two examples in which friction is not wanted?
In machine components, such as bearings or gears, excessive friction can lead to wear and reduce efficiency. In sports, like ice skating or skiing, minimizing friction is desired to allow for smooth and fast movement.
How do you reduce the friction and vice versa?
Reduce the friction . . .Apply lubricant to the surfaces in contact, or reduce the mutual pressure.Friction the reduce . . .The phrase has no physical significance.
What material can reduce friction?
Materials that can reduce friction include lubricants such as oil, grease, and wax, as well as low-friction materials like Teflon and graphite. Using smooth surfaces or adding ball bearings can also help reduce friction.
How is the friction involved in sledding and skiing?
Friction is involved in sledding and skiing as it helps to slow down and control the speed of the sled or skis. The amount of friction can be adjusted by the type of surface being traversed, the angle of descent, and the materials used on the sled or skis. Friction also helps provide traction and stability, allowing the rider to steer and maneuver effectively.

Does skiing have static friction?
Yes, skiing involves static friction, particularly when the skis are at rest or moving slowly on the snow. Static friction occurs between the ski base and the snow, helping to grip the surface and prevent slipping. As the skier gains speed, kinetic friction takes over, allowing for smoother gliding. Proper ski maintenance, including waxing, can reduce friction for better performance.

What role does friction have in the energy transformations of a person skiing downhill?
Friction plays a crucial role in the energy transformations of a person skiing downhill by converting some of the skier's kinetic energy into thermal energy. As the skis glide over the snow, friction between the skis and the snow surface generates heat, which can slow the skier down. While this energy loss can reduce speed, it also helps control the skier's descent, allowing for maneuverability and stability. Overall, friction is essential for balancing speed and control while skiing.
How the law of friction affects down hill skiing?
if there is friction on the hill it will slow you down
Which are the 2 friction forces that slow skiing down?
Air resistance and friction with the snow.
Does cleaning a pan writing a letter skiing require friction?
Yes, cleaning a pan, writing a letter, and skiing all require friction. In cleaning a pan, friction helps remove food residue from the surface. When writing a letter, friction between the pen and paper allows for ink transfer and legible writing. In skiing, friction between the skis and snow affects speed and control.
Do wheels reduce friction?
yes because when they brake the friction is caused to reduce
What kind of friction can help reduce friction?
I never heard of friction reducing friction. You can reduce friction by using lubricants, as well as using wheels (as in ball bearings).
What kind of force is skiing downhill?
Gravity but the snow provides friction
How does oil reduce air friction?
Oil is mainly used to reduce friction between contacting surface, e.g., metal on metal - not to reduce air friction.
What does a bit of oil reduce in science?
Oil is used to reduce friction.
