What Physics Teachers Get Wrong About Tides

Everything you’ve learned about tides is WRONG. We know that gravity affects the motion of all objects equally – so why are oceans the only bodies of water with tides? Join Gabe on this week’s episode of PBS Space Time as he sets the record straight on tidal force, gravitational differential and what role the moon actually plays in tides. Why don’t lakes have tides? Watch the episode to find out!” (YouTube)

Interesting video by PBS Digital Studios Space Time, explaining how tides actually work, and why what we’re often taught is wrong. It’s all to do with spots. Onwards!
