Python Physics: What Causes the Tides and How Do You Model Them?

This is part of my classical mechanics series. You can find all my videos in the series in the following playlist.

What causes the tides on Earth and how can you model them with python?

Here is the code

This is so cool! I suppose the acceleration due to the rotation of the earth is small enough to not affect the visualization

Twice a day.
Really excellent, Dr. Allain.

marvellous !
(as usual)
Often explained on YouTube, never this clearly.

Do you think a similar video could give an
intuitive feel for the semi-diurnal atmospheric tides ?

A difficult concept, Lord Kelvin got it wrong.

That was fun! Really interesting too, especially with VPython.

Thank you for this. You are the best. Keep these python videos coming. ❤

Tides is a quite complicated topic and sadly most (high school) textbooks are either plain wrong or kinda wrong/misleading. Had to do my own graphics for teaching this.
What is really important is the fact that tides you see are not generated by the water level "below" the moon just being pulled upwards.
If that was the case then sitting at the beach with a glass of coke would be impossible as every 12h your drink would just 'jump' out of the glass - it obviously does not.
What creates tides is the vast amount of water from the regions near the poles being pulled towards the equator. This is why a lake also has no tides despite an ocean next to it might have them.

Great stuff. PBS Spacetime, another great science education channel, did a video on tides quite a few years ago. But they don't go into the math.

Great stuff! As usual! Can you make the tide-wave move around the world? Animation-wise?

Why did you declare N? Also n += 1 :) Good stuff, though!
