Question

Why is it easy to slip when there is water on the floor?
(A) The water is a lubricant and reduces the friction between your feet and the floor.
(B) The friction between your feet and the floor changes from kinetic to static friction.
(C) The water increases the friction between your feet and the floor.
(D) The friction between your feet and the floor changes from sliding kinetic friction to rolling kinetic friction.

Answer 1

Hint: As we all know that on rough surfaces we do not slip easily, because there is a lot of friction between our feet and the surface to balance us on our feet. But lubricant can reduce the friction between two surfaces.

Complete answer:
Water acts as a lubricant and reduces friction between your feet and the floor.
Because wet flooring has less friction, we slip. This is because when a lubricant is put between the two kinetic or static surfaces, the coefficient of friction and hence the resulting force of limiting friction is greatly lowered.
The nature of the two surfaces determines whether or not water works as a lubricant. Water must lower the contact area between two surfaces by separating them and serving as a barrier in order to reduce friction. It can only do so if neither surface absorbs water; otherwise, the water will not stay between them.
Objects travelling through fluids like air or water are also subjected to frictional forces, which slow them down. This is referred to as drag. Friction stops or slows the movement of items. It also wears down surfaces and generates heat as they rub against each other.
Hence, the correct option is (A) The water is a lubricant and reduces the friction between your feet and the floor.

Note:
In the actual world, frictionless planes do not exist. If they did, though, items on them would almost certainly behave exactly as Galileo predicted. Despite their absence, they play an important role in the design of engines, motors, highways, and even tow-truck beds, to name a few.
