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

I’m watching this a day before half yearly exam
Mine is tomorrow bro 😂😂
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
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.
Broo just kee pessing 15:13 and it seems like he is clappingg🎉🎉🎉🎉❤❤
I Think the minimum value of static friction is
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.
😊
😊
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
The sportman wears the shoewith spikes becaues it will provide more grip therefore the friction will become more
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
Is friction present in a vacuum?
Please explain. Thnxx
No
There is no friction in 🌌 space
No, because there is no friction in the space.
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
Ans - sportsman use shoe with spikes because spikes produce the desired frictional force and thus help in holding the ground firmly
15:13 15:13 15:13 15:13
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.
Can you repeat the static friction
2 nd comment pls like kar ke viral kar do 😀🙏🤞
The sportsmen use shoes with spikes because it interlocks with the floor and gives a better grip making the chances of injury decrease
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.
What is sp9ke
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.
I like the way he teaches😊....
Congrats byjus for getting such an amazing tutor.....🎉🎉😊😊
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.
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.
We cannot walk at the Soapy water place which fall on the marble floor because its reduce the friction that acting to the marble and we will fall on it
Yes, it is difficulty to walk on soapy water because of following reasons
* There having lower friction
* Both surface area are sooth
15:12 that ooohhhhoooo 😂😂❤❤
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
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
Homework
Sir we won't be able to walk on the flour because the friction will decrease and we will keep falling 🍁🎉
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
nice answer sis
Good one 👍👍👍👍

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

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 .
i have cbse exam tmro class 8-10 same paper
It is hard to walk in soapy water because friction is less because of slippery floor 😊
to increase the friction and to maintain grip
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.
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.
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.

100% really before
Good luck for half yearly exam😂😂
Sportsman uses shoes with spike because to increase the friction between shoes and the ground
zero is the lowest value for static friction..
Do like who came here to prepare for annual exam😂😂
Best of luch of tommorows exam 😂🎉
1=they use spikes because it increases friction and gives them a nice grip
2=difficult to walk because friction decrease between foot and floor
Tq sir
Minimum value of static friction is zero.
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
The spikes will help in preventing the sport player from slipping on the ground
Oooo nice answer
Me also
when a sportman use spiked shoes a it is rough the friction increases and the sports can easily run without sliping on land
it makes difficult to walk because when we spill of water on floor it decreases the friction and its easier to slide on floor
Like if you came here before one day of annual exam😂😂😅😊🎉
Sir plz start the finger abaccus sereies i want part 4
they use spikes to get more grip on the ground or else they will slip
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.
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.
Talk. In English 😂
The sportsmen use shoes with spikes because it increases friction by interlocking with the soil by increasing the pressure.

the "tak tak tak tak tshh" to explain friction on a carrom board is epic 😅🤯🤯
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
My favorite sir
Spikes will provide larger frictional force than normal shoes. The spikes will help the players from slipping on the ground
Sportsmen use shoes with spikes, also known as studs, to increase friction and grip on the ground while running or walking
Hi

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
Half early examss
Sir ur head i soo polished that friction Doesn't act there
Sir, the soap water fills the groove or irregularities of the surface therefore, friction between two surfaces becomes less 16:46
Becouse decrease friction my answer is this
Bro my opinion is they should add their own subtitles because these youtube ones are in white and have a black background soo.. and they are fat who ever thinks these pls like so they can add it it not only helps me but can help a lot of peeps you think I am an old aunty but nahhhh I am a 8th grader😂😂😂😂😂😂
Mid term legends
Same bro
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.
legends are watchin onr day before exam
me too
