What is one situation that friction is useful?
Friction plays a vital role in our daily life. Without friction we are handicap.1. It is becomes difficult to walk on a slippery road due to low friction. When we move on ice, it becomes difficult to walk due to low friction of ice.2. We can not fix nail in the wood or wall if there is no friction. It is friction which holds the nail.3. A horse can not pull a cart unless friction furnishes him a secure foothold.
Why a wheel cannot roll without friction?
Walking would not be impossible, but it would be likened to trying to walk on ice. Friction opposes movement, which can also be translated into traction. The more friction, the more of an opposing force the object will feel. Since ice has no friction, slipping and sliding is a problem to deal with. But since the majority of ground material on Earth has some type of friction, the opposing force that it provides also allows the feet to remain firmly planted on the ground rather than slipping out from underneath.
Tell you some apllications of rolling friction?
A wheel is an example of rolling friction. An example of rolling friction would be if you took kyle leary and folled him down a hill. his fat touching the grond would create rolling friction
How does friction help athletes?
Wow, without friction we'd be playing different games, that's for sure. Let's see, runners use the friction between their shoes and the track to impart forward motion to their bodies. Otherwise it would be like running on ice. Soccer players use friction between the air and the soccer ball to bend it like Beckham. As they kick the ball they impart spin and through a process involving friction with the air among other things, the ball will curve. Without friction, pole vaulters would plant their pole and then just slide along it. The friction between their hands and their poles allows them to turn their forward momentum into vertical lift. Friction is what keeps the football in the quarterback's hand until he let's go and it allows the receiver to catch the ball. Friction between the ground and shoe is used again when a Baseball player rounds the bases. Assuming he was moving toward 1st base, without friction he'd slide right past and into the outfield. Friction allows him to plant his foot and turn towards 2nd. I'm sure you can also come up with a dozen different examples just like the ones I've given
Why do your fingers have friction ridges?
Your fingers have friction ridges so that we can grab or catch or even hold things with our fingers. If we did not have these friction ridges then probably we wouldn't be able to hold things without the help of our fingers.
What would be like to climb a rope without friction?
Without friction - climbing a rope would be impossible !
How does the friction force help people in walking?
Without friction it would be impossible to stand, you would instantly fall down flat. Without friction it would be impossible to crawl. Without friction the only way it would be possible to move would be by using thruster jets, as they do on spaceships.
Is friction usefull in playgrounds?
Friction is fascinating because in so many situations we try to reduce friction, but friction is a necessary force, without which everything would be impossible. Without friction we would all be flat on the floor without any methods of directing our motion. We would randomly collide with things and then continuing moving in another direction. Without friction the slide at the playground would be really fast, but you could never climb the ladder to get on it. The swings would be useless since no one could get into them. So friction is necessary for playgrounds.
Would walking impossible without rolling friction?
Yes it would, thank God for rolling friction
Do you need friction for typing on a keyboard . why?
Because without friction, it would not be successful when typing!
Why do you need friction on a surfboard?
Without friction, your feet would just slip right off.
What happens if there were no friction?
Without friction, objects would have no resistance, therefor loose no energy as a result. For example, without friction a ball could roll up and down a half-pipe continusily without loosing hight.
What would there be without friction?
it would be nearly impossible to stop cuz it is slippery
Would walking be impossible without sliding friction?
Yes it would, thank God for rolling friction
Why do you need friction on animals?
Because without the friction on animals the the neutrons of the atoms would not be able to work properly.
Why is friction important in life?
Without friction you - and everything else - would simply slide off all the time.
Why would machines work better without friction?
The smaller amount of friction a machine has, the more efficient it becomes.
