Spikes will provide larger frictional force than the normal shoes. The spikes will help in preventing the sports players from slipping on the ground.

A1=Sports men use shoes with spikes to increase the friction between shoes and the surface. The shoes with spikes do not slip while they run or play. A2=The layer of soap makes floor smooth due to which the friction is reduced and the foot cannot make a proper grip on the flore. Therefore, it is difficult to walk on a soapy floor and we start to sleep on the floor. 😊

[@advita11-t8d]

16:05 Answer: Sportsmen use studs (shoes with spikes) bcoz they need to run fast and they can slip easily without studs as studs increase friction. (spikes interlock with the surface)

[@Ineshmahendera]

Sir, the soap water fills the groove or irregularities of the surface therefore, friction between two surfaces becomes less 16:46

[@advita11-t8d]

16:43 Answer: it would be tougher to walk on the soapy marble floor. Marble is a slippery surface and soap water can make it more tough to walk as it also reduces friction.

The spikes will help in preventing the sport player from slipping on the ground

[@naziyabegam5689]

Oooo nice answer

[@kalpadipakmeshram]

Q 1. To increase friction and prevent slipping. Q 2. It will make it a lot harder for us to walk as we can slip at any moment.

[@KartikStudies-cj8yf]

16:49 when the soapy water is spilled. It reduces the friction by filling the irregularities present on the surface of the floor. Thus, this makes walking difficult on the floor on which soapy water was spilled.

[@rekhadahiya7189]

3. It is more difficult to walk on a soapy floor because on that kind of floor irregularities and interlocking would be decreased that's why friction is decreased and friction as our friend first example is to walk properly friction help us if friction is not there we can't able to move we slip again and again because the floor can't make irregularities and interlocking with our soles of shoes hence, it is difficult to walk on the soapy floor

[@GuntaDileswer]

[@ayeshabintpawan9673]

What a slippery situation! Imagine the marble floor as a sleek, shiny runway, and I'm the hapless model who's just spilled a bucket of soapy water all over it. Suddenly, the floor transforms into a slippery slope - literally! As I try to take a step forward, my feet feel like they're ice-skating on a frozen pond. The soapy water creates a thin layer of lubrication, making it incredibly difficult to get a good grip on the floor. It's like trying to walk on a banana peel - not exactly the most stable or dignified experience! Every step becomes a precarious balancing act, as I struggle to maintain my footing on the slick surface. My legs start to wobble, and my arms flail wildly, like a bird in flight, as I desperately try to regain my balance. It's a miracle I don't end up on my backside! So, to answer your question, spilling a bucket of soapy water on a marble floor makes it significantly more difficult to walk on the floor. It's a slippery slope indeed - one that requires extreme caution, a sense of humor, and possibly a pair of ice skates!

[@D.VTejesh]

16:00 ans :- sportsmen use shoes with spikes because , it increases friction between shoes and the surface . So, while sportsmen play with shoes with spikes it helps to run or play without slipping on the floor .

The spikes will help in preventing the sports players from slipping on the ground. Hence sportsmen use shoes with spikes. Spikes increase the surface of the shoes & make it rough which results in an increase in friction. This helps to have more grip on the floor and chances to slip reduces.

[@shlokmane2989]

Its is difficult to walk on the marble floor with soapy water on it because soapy water forms a thin layer between irregularities present on our feet and the floor This reduces interlocking of irregularities and thereby reduce friction

[@PraveenKumar-pb5nk]

The force of friction pushes it in the forward direction and allows us to walk. The force of friction between the ground and feet decreases when there is soapy water spilled on the floor. Hence, it becomes difficult to walk on the soapy floor.

[@RY0M3N_SUKUNA.]

16:19 It would be more difficult to walk on the floor because the gaps of the surface are filled by soapy water and there would be no position to get grip on it

[@scavaep]

they use spikes to get more grip on the ground or else they will slip

[@DhritiMajumdar]

A1= sportsmen wear shoes with spikes underneath because the spikes increase irregularities, therefore increasing friction and giving them better grip on the ground. A2 = spilling soapy water on marble floor will make it harder for us to walk because marbel is already a smooth surface and soapy water, being a lubricant, would block the few irregularities present therefore decreasing friction

[@amsavenim480]

Hw 1. Sliding friction is less than static friction because it is easier to move an object that is already moving compared to the object which tends to move. 2.Sportsmen use shoes with spikes as they prevent them from slipping and by were the sp9kes increase friction by giving them better grip. 3.If I spilt the soapy water on the marble floor it would make me walk difficult as soapy water makes the floor smooth and reduces friction which makes the floor slippery.

The sportsman's use shoes with Spikes because it's increase the friction of the road and take in they can run fast faster as compared to run with normal shoes

[@HarmonyofHosannas7]

Homework Answer: It makes it harder to move. Friction makes walking on the floor possible. To walk on a floor, we push the ground backwards with one foot while the other foot is being lifted for a step forwards. Without friction, we can't one foot on the ground firmly due to which the body can lose balance and make us fall. When soapy water is spilt on a floor, the friction between the floor and the foot is reduced drastically. This makes the floor slippery and difficult to walk on.

[@mamtaGupta8383]

Sportsmen use shoes with spikes because of the better grip given by spikes while running. This is because the force of friction between the shoes and the ground increases with the help of spikes.

[@knowledgeandgamesofaadvikh568]

The sportsmen use shoes with spikes because it increases friction by interlocking with the soil by increasing the pressure.

[@skywalker5932]

It is possible to walk on the floor because of the friction present between our feet and the ground. For walking, we push the ground in a backward direction with our feet. The force of friction pushes it in the forward direction and allows us to walk. The force of friction decreases between the ground and the feet when there is soapy water spilt on the floor. Hence, it becomes difficult to walk on the soapy floor.

[@RouhanKhan-rf7cp]

Sportspersons use spikes shoes because it helps us to get proper grip because of interlocking between irregularities and also because of bond formation, this helps us to attain strong grip between shoes and the surface of contact

Homework question / Ans It is very difficult to walk on the floor that have soapy water spilled on it because it fill all the interlocking between floor with water that is why it is very difficult to walk on a soapy floor because it reduces the contact of shoes with the surface that decreases friction between shoes and the surface of contact

[@creativesreesha9561]

See so sopay water acts like a lubricant which makes difficult for us to walk because lubricants reduce friction and our foot doesn't make interlocking with the surface as lubricant is present .

[@harshgajraj6700]

Spikes increase the surface of the shoes & make it rough which results in an increase in friction. This helps to have more grip on the floor, and the chances of slipping are reduced. This makes it easy for sportsmen to walk or run as their grip on the ground increases.

[@devishigupta4722]

This is because due to the spikes in the shoes, the surface will be rough, and due to which there will be more friction which prevent the slipping of sporteman while running

[@Manojkumar-dy8yd]

The sportman wears the shoewith spikes becaues it will provide more grip therefore the friction will become more

[@naitiksworld7624]

Sportsmen use shoes with spikes, also known as studs, to increase friction and grip on the ground while running or walking

[@rajivkumar-2987]

9:10 static friction before sliding starts

[@sndanger9341]

If spilled soapy water on a marbel floor it becomes more difficult for us to walk on that floor because as we know that smooth surface makes the friction lesser . So, it becomes difficult for us to walk on that floor. We can even slip on that soapy floor.

[@KSain-qo5cj]
