What else can I help you with?
Why would have wet surfaces on the inside of the lungs be useful?
It allows the lungs to inflate and deflate without the "walls" sticking to each other, acting as a lubricant.
What kind of friction allows wheels to turn without spinning on a surface?
Rolling friction :)
What is the purpose of the valve stem on a bike tire?
The valve stem on a bike tire is used to inflate and deflate the tire. It allows air to be pumped into the tire to reach the desired pressure for optimal performance and safety while riding.
What kind of friction allows you to walk without slipping?
Alternately, as we step: sliding, or dynamic friction; static friction; sliding friction again. Sequence repeats with each step.
Is it true you could not walk without friction?
Friction is actually what allows us to walk. When we take a step, the friction between our feet and the ground provides the necessary force to propel us forward. Without friction, we wouldn't be able to generate the traction needed to walk.
Why is it important to have cartilage around the end of bone?
Allows joints to move smoothly and without friction.
What is the necessity of friction?
Friction is necessary because it allows objects to grip and move against each other. Without friction, objects would slide uncontrollably and it would be difficult to walk, drive, or even hold onto objects. Friction also allows us to stop motion and control speed.
Does shoelace have high or low friction?
Shoelaces generally have low friction, making them easier to tie and untie. This low friction allows them to slide through the eyelets of shoes smoothly without getting stuck.
Is it true you could not drink from a glass without friction?
It is true that drinking from a glass without friction can be challenging because the liquid would not stay inside the glass due to lack of adherence. Friction between the liquid and the glass allows the liquid to be lifted and contained for consumption.
What is desirable effect of friction?
The desirable effect of friction is that it allows us to walk, drive, and grip objects without slipping. This type of friction also helps us stop moving objects and control their speed.
Is writing on a chalkboard friction?
Of course Yes... Without friction we wouldn't be writing on chalkboards!!
What are 3 ways friction is useful?
It allows you to walk (with out friction between you and the floor this wouldn't be possible) It is needed for braking can be used to produce heat
