While on tour during my stint in the U.S. Navy I encountered a whirlpool in the South Atlantic Ocean, though it was a small one it was still fascinating. Today I found out that it was a parabolas, I had no idea what a Parabola was until I googled it. There are Parabolas all over the world, a parabolas is the curve formed from all the points (x, y) that are equidistant from the directrix and the focus. The line perpendicular to the directrix and passing through the focus (that’s the line that splits the parabola in the middle) is called the "axis of symmetry"(Stapel). The parabolas I found interesting was the whirlpool, it has the curve formed from every point and equidistant from the directrix of the focus, it also has a line perpendicular to the directrix and passes through the focus; which is called the "axis of symmetry"(Stapel).

Unformatted text preview: making of a whirlpool consists of liquid, gravity, and centrifugal force, when liquid is rotated, the forces of gravity meet the centrifugal force, which results in the liquid forming a parabola shape. The most common example of parabolas is a whirlpool; it rotates around its axis. The water level rises even with the water surface while falling slightly in the center of the parabolas (the axis) (London). Now that I know what a parabolas is I see them everywhere, it’s funny because you do learn something every day. Winston Reference London, J. (n.d.). Real Life Parabola Examples.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
