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.

[@onlystudy886]

A1=They use spikes because it gives them better grip and it increases Friction. A2=It is hard to walk on soapy floor because it has less friction and smooth surface. Thanks Sir

[@Vineshow8754]

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. 😊

[@OmParkash-ie8ls]

[@Ineshmahendera]

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

[@Snapshot7999]

Sir, When the soapy water is poured on marble stairs it Will decrease the frictional force as a result we will not be able to walk on the stairs infact we are gonna fall in fact of walking

[@avayasahoo5634]

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.

[@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]

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.

[@Satya_jit952]

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

[@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.

[@Dazzlinq-s5g]

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

[@Manojkumar-dy8yd]

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

[@knowledgeandgamesofaadvikh568]

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

[@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

[@GuntaDileswer]

when a sportman use spiked shoes a it is rough the friction increases and the sports can easily run without sliping on land

[@Arbi_nahi_Urvee]

15:12 that ooohhhhoooo 😂😂❤❤

[@best4yu001]

Ans - sportsman use shoe with spikes because spikes produce the desired frictional force and thus help in holding the ground firmly

[@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

[@naitiksworld7624]

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

[@GuntaDileswer]

it makes difficult to walk because when we spill of water on floor it decreases the friction and its easier to slide on floor

[@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.

[@Nandini-n8f]

Spikes increase the surface of the shoes & make it rough which results in an increase in friction.

[@sumanwaghamore1521]

Sportsman uses shoes with spike because to increase the friction between shoes and the ground

[@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

It is hard to walk on the floor which has soapy water spilled over the it becuz the friction get decreased

[@SatveerKasana-y4v]

Thank you Sir It helps me a lot

[@lavanyaks555]

Because, sports man use shoes with spikes to get a better grip on the ground spikes act as irregularities and help in increasing friction...

[@AtomicStudent]

Homework Sir we won't be able to walk on the flour because the friction will decrease and we will keep falling 🍁🎉

[@AnandKumar-dv2pw]

13:45 that powder is a coarse substance

[@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.

[@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.

[@GiveMeANameToPutHere]

Very well explained ngl

[@funnyxgamerak]

The sportsmans use the shoes with spikes because they have to run but to run they need friction so they use shoes with spikes to get better grip

[@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 .

The spikes provide better grip in ground and also helps for prevent slipping

[@funnyxgamerak]

It makes us difficult to walk in soapy water because it has less friction compared to the floor which has more friction so we may get slipped while walking in the soapy water

[@chikkibahuguna8431]

11:15 I have no enemies

[@bhavayagupta350]

and then friction comes

[@User_109-_23]

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.

It would be difficult to walk on the floor because due to the soapy water spilt on the floor, the surface would get smoother due to which friction will be less, and thus we will tend to slip.

[@naitiksworld7624]

Minimum value of static friction is zero.

[@pramodsharma5514]

[@SankarSubhu]

Hw. It makes it more to walk easier because smooth and wet surface would reduce friction . It may make you slip and fall sometimes because friction is less and the grip is also less

[@shantiprasadsharma9615]

As the friction decreases, it is more difficult to walk on that floor

[@harshgajraj6700]

Walking on a soapy floor is more difficult because the soap layer makes the floor smooth. Soapy water reduces friction, and the foot cannot properly grip the floor.

[@pinkigupta2180]

Can you repeat the static friction

[@kishormali6956]

Homework answer :- it will be more difficult to walk on the floor because there will be a layer of water in between the sole of anf floor which reduce 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.
