How do forces like friction help us?
friction slows us down if it wasn't for friction everyone would be slipping everywhere
Simple way of explaining surface roughness?
Generally surface roughness increases friction. For example, take a piece of course sandpaper and rub it on a piece of wood. The smooth side will slide easier to slide on the wood than the rough side.Then you might ask why Indy Car tires are smooth.Groves were put in tires to wick water away from between the surface of the road and the tire to prevent hydroplaning.Indy tires are run on dry surfaces. And, the lack of groves increases the surface area. Also note they use very very grippy rubber, kind of like the paper separation rollers on a laser printer.Another exception might be that very smooth, flat items stuck together can form a seal, with or without the presence of a lubricant like grease or water. A seal can increase friction more than would otherwise be expected.Surface roughness or imperfections can break the seal and decrease friction.One final note is that the surface dimpling on a golf ball might actually help make a static air buffer around the golf ball and decrease it's air friction.
Do CDs have low friction?
If you are talking about a CD or CD ROM then yes. When I was in Middle School we had a project where we made balloon powerd cars. I made my car have CD wheels and it went far. CD's have a smooth wheel like structure. A wheel can help prevent friction, so the CD's circular shape enables it to have less friction.
How friction help standing on a shower mat?
Without friction an object in motion would continue in motion unless acted upon by an outside force. Friction in this case is providing traction, so you can actually resist sliding. Shower mats increase friction, and reduce sliding. This friction is caused by physical imperfections within the two surfaces (feet & shower mat) when in contact with each other.
What thing can you use to help us overcome friction?
wheels overcome friction
Does friction help to increase gas mileage?
False
What provides a smooth slippery surface over bones to help reduce friction?
cartilage
How does the uneven surface of the rubber soles of your shoes help to increase the friction on a rainy day?
that will increase the total surface area of the base of the shoe and thus will increase the friction force and this help a lot ex-specially on rainy day
Does Friction help increase gas milage?
No, friction decreases gas mileage. If you are talking about Friction motor treatment then it is just another in a long line of products claiming to increase mileage. None of them work, period.
How do the studs on the football boots and the spikes on running shoes help the athletes?
increase friction
How the nubrication help in reducing?
Lubrication will help in reducing friction in a very smooth manner. It is a process that prevents solid to solid contact which would cause friction. You would need to use a lubricant such as oil or water for lubrication.
Why do friction is high in very smooth surfsces?
i honestly didnt get ur ans but ill still try to help u out.. friction is the opposing force to a motion, when the surface is very smooth friction reduces.. i.e the smoother the surface the less the friction.. for eg.. if u spill oil on the road the car starts slipping and becomes hard to stop it i.e bcos the surface becms smoother and reduces friction..

What are some ways to increasing friction?
Use a surface that has a higher coefficient of static/kinetic friction and/or add more force downwards on the object.
How do you help a dog with itchy feet?
Make them walk on sandpaper.
Would it be better to increase or decrease friction in swimming?
If you want to swim faster, then decreasing friction would help you with that - Less friction means you glide easer through the water. If you want a more efficient workout then increasing friction would help you with that. If you were to put a track suit on before entering the water you'd have to work a lot harder for each lap in the pool.
