Why do drops of water slide down a smooth surface faster than drops of oil?
Why do drops of water slide down a smooth surface faster than drops of oil? Because of viscosity. Water is very different from oil. It pours easily, and it is not thick and sticky like oil.It is more dense than oil.
What makes a slide go faster?
Different things affect how fast you move down a slide. The surface of the slide, the clothes you are wearing, how heavy you are, and the amount of your body touching the slide all make a difference. Whether the slide is flat, wavy, or spiral makes a difference too.
Why does water flow faster than vegetable oil?
A great example comparing viscosity with density is oil and water. Oil is less dense than water (it floats on top of water) but more viscous than water. Oil resists flowing, where water flows more easily.
