Question

11. (a)What downward force is acting on you when you go down a waterslide? (b)What type of friction is

present? (c)If the waterslide were dry explain what type of friction in would be and (d)how that
changes your speed? (4 points)

Answer 1

a) "gravitation" is the force causing you to go down a waterslide

b) It is "fluid friction" as a solid object (our body) moves over a fluid (the water)

c) It would become "sliding friction" since two solid surfaces slide over each other

d) fluid friction being the weakest friction, switching to sliding friction means a higher decrease in speed and therefore removing the water from a slide will decrease our speed
