Tides pull and deform the surface of the ocean and the surface of the Earth. This week we’ll take a quick tour of tidal forces, address some show feedback, and then talk about a revision on a classic physics problem.
We’ve all had to solve the classic physics problem of what would happen if you dug a tunnel through the center of the Earth and jumped in. The classic answer has been that you’ll move like a damped oscillator and that your fall will take about 42 minutes. By improving some of the assumptions that are used, that answer has been improved.
