The pencil would just slide out of your hand because there would be nothing holding it there. You would have to balance the pencil on your hand!

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 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.
What are the 3 kinds of friction describe each?
sliding friction is like sliding a desk without wheels across a floor since its sliding and if there a large amount of weight involved it will be harter to over come the friction , rooling friction is like a skateboard rooling down the street for rooling friction the object NEEDS to have wheels or it wouldn't be rooling friction,and fluid friction is like droping a ball through air since air has water particles and counts for fluid friction.
Why would friction affect gravity?
Gravitational acceleration is a constant value for a celestial body, and doesn't depend on air resistance/friction. The value on Earth is constant anywhere on Earth, just like the value on Mars is constant anywhere on Mars. In practical,however, this is different. Air resistance lowers the value of gravitational acceleration.
Examples of high friction?
Example of high friction is a really rough surface like sandpaper.
What would be like to climb a rope without friction?
Without friction - climbing a rope would be impossible !
Would walking be impossible without sliding friction?
Yes it would, thank God for rolling friction
What would one persons life be like without friction?
Everything will be in motion wihtout no control.
How does friction help you walk?
It gives you grip on the ground. Without it perhaps it would be like ice?
Would you like to put your pencil in my pencil sharpener?
no thank you
Is friction useful to footballers?
yes, without it the play field would act like a skating rink!
What would a game of soccer be like with friction?
Friction is essential for Walking and other movement. So obviously it is of paramount importance in football. Without friction, A player can't grip the ball, the ground pr other players. Running, which is the base of football, doesnt exist without friction. Hence, no friction = no football.
Friction as a foe?
yes it a foe but without friction in our like we cannot like. when there is no friction we cannot walk or no body can stand on the surface because were there is less friction we cannot stand it will be smooth
What are 3 types of kinetic friction?
1. Our cars would get much better gas mileage without tire and air friction. 2. There would be no more skinned knees if friction didn't exist. (Like when you are skating or playing football.) 3. We wouldn't have to worry about clothes chaffing us in dry weather if there were no friction. 4. We could do some pretty amazing dance moves without friction. (The Electric Slide would last forever....) 5. Our shoes would last a lot longer without friction.
What your life would be like without friction?
Without frictin life would be very slippery. This topic has been explored in a novel by Philip Jose Farmer entitled "The Lavalite World".
How would it be like in a world without friction?
you would be sliding and jumping all around just imagine there's nothing t pull you down
When is heat from friction helpful and when is it harmful?
Helpful:1. We use it to brake our cars2. We use it to fly our airplanes. (The friction of air on the wing causes the plane to stay airborne).3. We would slip and fall if there were no friction between the ground and our shoes (demonstrated by an icy sidewalk...).4. We wouldn't be able to turn a doorknob without friction. (Our hand would just slide off of it.)5. We can warm our bodies by friction. (When campers get lost, they can rub their chest, arms and legs to create warmth by friction)Harmful:1. Our cars would get much better gas mileage without tire and air friction.2. There would be no more skinned knees if friction didn't exist. (Like when you are skating or playing football.)3. We wouldn't have to worry about clothes chaffing us in dry weather if there were no friction.4. We could do some pretty amazing dance moves without friction.
