Why is it difficult to strike a match on a smooth surface?
It is difficult to strike a match on a smooth surface because the friction needed to ignite the match head is lacking. Matchboxes and striker surfaces are designed to provide enough friction for the match head to ignite when rubbed against them. Smooth surfaces do not create enough friction to generate the heat required to light the match.
Is greater force needed to move an object over a smooth surface than over a rough surface?
No, greater force is typically needed to move an object over a rough surface compared to a smooth surface. This is because the irregularities on a rough surface create more friction, making it harder to overcome resistance and move the object. Smooth surfaces offer less resistance to movement.
What are the most difficult surface to maintain any type of friction?
The most difficult surfaces to maintain friction on are typically those that are very smooth, non-porous, and have low coefficient of friction materials like ice or glass. These surfaces offer little to no resistance to objects moving across them, making it challenging to generate or maintain friction.
What type of friction does air offer?
Air offers fluid friction, known as air resistance. It is the force that opposes the motion of an object moving through the air. This friction increases as the speed and surface area of the object increase.
What material can you use to paint your cement walls to make them more smooth?
A good Latex paint, or satin finish paint will offer a smooth, and easy to clean surface...granted the surface is within a living area of your home. A basement area needs to be waterproofed before hand.
Can compression elbows on the hot and cold water supply pipes to a gravity fed shower reduce water pressure?
Yes as the short radius fittings offer greater friction losses
What are the benefits of choosing fiberglass pool steps for your swimming pool?
Fiberglass pool steps offer benefits such as durability, low maintenance, slip resistance, and a smooth surface that is gentle on feet.
Why do drag racing tires have no tread - isn't tread supposed to increase traction?
In ideal conditions, dry weather, great road surface etc. slick tyres offer more rubber to the road therefore greater traction. Normal road tyres are a compromise, on any one trip your car may have to cope with sunshine, rain, sleet, snow, bad road surface, smooth surface, mud, and gravel. Manufacturers have to make a tyre that can cope with that. The result is the tyre on your car.
How do object move different surfaces?
Objects move on different surfaces by friction.
Which surface friction is the highest carpet plastic wood marble?
carpet has the most fictionThis cannot be answered really. Friction requires 2 surfaces in contact with each other . Rubber on Wood, has a high coefficient of friction, but plastic on wood has a low coefficient of friction. You must state , the make of the material you are going to use to slide over the Carpet, or Plastic, or Wood. Also , different types of carpet or plastic or wood will have very different friction coefficients. Example Nylon carpet is very easy to slide things along, but wool or cotton carpet is a very different story. There are many types of plastic which are rubbery in nature and they offer a lot of frictional resistance.
What does pantene offer you?
pantene offers you shiny, smooth and full hair
How does friction affect the motion of a vehicle in the context of tire surface road conditions including skidding braking force braking distance thinking distance and stopping distance?
Tyre surface: If the tyre is new, it will have surface with depressions which will offer more friction compared to old tyre whose surface-depressions are worn out and it is more flat, so it offers less friction. Therefore, new tyre will have less stopping distance, as force of friction is more. Thinking distance is affected neither by friction between tyre and road, nor by friction between brake and tyre. If road has a wet surface, it has less friction so the vehicle will skid farther, and vice versa. The braking force, i.e, friction between tyre and brake is unaffected by road condition or tyre surface. Hence the distance the vehicle travels WHILE retarding due to "braking force", is not same as stopping distance, because even when the wheels are stopped rotating due to braking force, the car will skid a little distance- this total distance is the stopping distance.
