    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.

    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

    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.

  • @HarmonyofHosannas7
    @HarmonyofHosannas75 ай бұрын

    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.
