DIFFERENTIALS!! 🙂 During class today, I talked about tides and how there is a great deal of misinformation out there. My favorite websites for the astronomical explanation of tides are: A rigorously correct but a tiny bit snarky treatment – it’s my favorite: Tidal Misconceptions by Dr. Donald E. Simanek One of the links from […] Continue reading → Continue reading
Generally, if you’ve ever been on the ocean, you understand the concept of tides. You put your umbrella and chair up at noon near the edge of the ocean and you fall asleep and you wake up a few hours later in the middle of the waves. You didn’t move, so the ocean had to… Continue reading → Continue reading
This video is a cool, informative, easy understand animation of how the gravitational pull between the Earth and the Moon affect tides. It clearly and concisely describes how tidal forces cause high tides twice per day even though the moon is only overhead once per day and why the gravity is weaker at a greater […] Continue reading → Continue reading
Having grown up near the ocean, I always found tides fascinating. Until now though, I never quite understood what was happening. Moon tides are caused by the Moon’s gravity which creates two “bulges.” Additionally, there are Sun tides, but these are not as strong due to how far away the Sun is. Recently, in the […] Continue reading → Continue reading
Many people know that tides rise and fall as a result of the Moon, but often times people are unaware that the Sun also exerts a tidal force on the Earth. Tides are caused by gravitational force, which depends on the mass of the objects pulling on each other and the distance between them. The […] Continue reading → Continue reading
Tides are created by the Moon’s gravitational pull on the Earth. While the Sun also pulls on the Earth, it is so far away that the tides are not as affected by the Sun as they are by the Moon. The tidal force is created by the difference in gravitational pull on each side of […] Continue reading → Continue reading
