Parabolic shapes in the real world

According to Wikipedia, that great internet source of both information and misinformation, “In nature, approximations of parabolas and paraboloids are found in many diverse situations.”

Begin by clicking Start a New Conversation. Research ONE example of a parabola in real life that has not already been used by a classmate. Make your choice (Bouncing ball) the subject of your post, and then tell us in your own words about your parabolic find (at least 150 words). Do not just make this up off the top of your head. The St Louis Arch, for example, is NOT a parabola—it is an inverted catenary.

To get credit for this Forum, you must cite a source confirming that your example is, indeed, parabolic and not some other more exotic curve. Using a personal example (My eyebrow) will not count unless you can cite a source verifying that eyebrows are parabolic.

You must also respond to 2 classmates’ posts in 50 words or more. You may ask questions to elicit a more in-depth explanation, add additional information to your own posting in response to questions, share additional knowledge on another post or share an example from your own life related to the topic.

Please sign ALL your Forum posts with the name that you like to be called – it makes it so much easier for the rest of us to address you by your preferred name when we respond.
