Science
You spill a bucket of soapy water on a marble floor accidentally. Would it make it easier or more difficult for you to walk on the floor? Why?
Answer
Spilling soapy water on a marble floor would make it more difficult to walk on the floor. When we push the floor in the backward direction with our feet, the force of friction pushes it in the forward direction and allows us to walk. The soap in the water creates a slippery surface, reducing friction between our feet and the marble floor. As a result, walking becomes more difficult on the slippery marble floor.
