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 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.
Why is it important to have cartilage around the end of bone?
Allows joints to move smoothly and without friction.
How do alveoli work?
The alveoli are located in the lungs. They are used to move carbon dioxide and oxygen between the lungs and the bloodstream.
What is the helpful effect of friction?
It enables us to move: without friction we would be in a permanent skid. It allows us to hold things: they would just slide away.
How does friction does affect your daily lives?
Walking on the ground. Car motion on the ground. Driving belts of the engines. Stopping of vehicles with friction pads. Get seated and secure in a car when it stops without hitting the windscreen. and a lot more. Friction between tyre and the road allows cars to move forward and stay on the road, as well as the friction between your feet and the floor allows you to move. Friction between break pads and wheels allows cars to break. Friction causes objects to lose energy through heat, ie when parts of a motor rub together.
How does friction hinder movement?
Friction allows the object to move more easily.
What is the friction that results from your tires interacting with the road that allows your vehicle to move forward?
This type of friction is called static friction.
The friction which allows a car's tires to grip the roadway?
This type of friction is called traction.
What is a sentence for friction?
It is friction that allows the brakes to work. The friction between the two was not helped by the competition. The heat in the bearings was being caused by the friction due to a lack of lubricant.
Could you ride a bike if there was no friction?
No. you would be unable to walk, jog, run or ride if it wernt for friction. one of the most powerful and fundimental forces on Earth. Friction Causes Heat and Heat Allows for grip. life would be very difficult to live without friction. Saying that, life would be no fun if there was friction everywhere... the last place you want friction is somewhere like a giant waterslide of something lol
