Spikes will provide larger frictional force than the normal shoes. The spikes will help in preventing the sports players from slipping on the ground.
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.
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.
14:08 the sound effects 🤌🤌 😂😂 but honestly you explain very well ❤❤
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

Oh my my
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
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.
the "tak tak tak tak tshh" to explain friction on a carrom board is epic 😅🤯🤯
The sportsmen use shoes with spikes because it increases friction by interlocking with the soil by increasing the pressure.
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
15:12 that ooohhhhoooo 😂😂❤❤
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
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
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
they use spikes to get more grip on the ground or else they will slip
when a sportman use spiked shoes a it is rough the friction increases and the sports can easily run without sliping on land
Homework Sir we won't be able to walk on the flour because the friction will decrease and we will keep falling 🍁🎉
It is hard to walk on the floor which has soapy water spilled over the it becuz the friction get decreased
it makes difficult to walk because when we spill of water on floor it decreases the friction and its easier to slide on 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.
The spikes will help in preventing the sport player from slipping on the ground

Oooo nice answer
Sir plz start the finger abaccus sereies i want part 4
As the friction decreases, it is more difficult to walk on that floor
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
That example of hand and car was excellent ❤🔥🔥
Thank you for your support and blessings to us and you are very good teacher 😊😊😊😊😊
Ans - sportsman use shoe with spikes because spikes produce the desired frictional force and thus help in holding the ground firmly
Me studying 3 months before exam 😅 I think I am only one 😢
It is hard to walk in soapy water because friction is less because of slippery floor 😊
I Think the minimum value of static friction is
Sportsman uses shoes with spike because to increase the friction between shoes and the ground
2 nd comment pls like kar ke viral kar do 😀🙏🤞
Is friction present in a vacuum? Please explain. Thnxx

No, because there is no friction in the space.
It is difficult to walk on the floor in which Soapy water is spilled because we know that the Soapy surface decrease the friction so, it became difficult to walk
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

Sir plz we want figer abacus series from khushboo ma'am Plz re start this series again❤❤
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
i have cbse exam tmro class 8-10 same paper
Thanku sir. Explained very well ✨
It is tough to woke on floor because it is more slippery and polishing at compare to before one it make it more tough
THANKYOUUUUU BYJUSSSS
I am watching this video 2 hours before exam

Spike increase the friction so we can easily walk on the ground
Sir ur head i soo polished that friction Doesn't act there
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
Sir ur head is soo polished that friction Does not act there

Homework - It is necessary because its help to get proper grip Then the person will not slip
Very well explained ngl
Hw Due to no shoes with spikes the sport men was slipped and out the game. 😊😊 Aparna Aditi

Homework question answer: Spikes and grooves are there in shoes and our traditional chappals, some times 🕊️ flying. To prevent falling while walking in rain, while playing and more... But main point Is to increase fiction. I know it relates. Especially when my friends face have the prints.

and then friction comes
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.

Good evening sir
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
Sir you are the best
sir u explained types of friction very nicely it made it easy
Becouse decrease friction my answer is this

If I spilt the soppy 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
THANK YOU SIR FOR THIS WONDERFULL SESSION IT WAS HELPED ME A LOT AND THANKS TO BYJUS TEAM
Thanks
Ultra legends study in just an 3 hour before exam 😢like me

So that it can create a rough surface to get more friction
Its written 30 mins but sir explained in 20
