    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

    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.

    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.

    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

    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.

  • @skywalker5932
    @skywalker5932 2 місяці тому

    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.

    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.
