Показать описание
Polar coordinates are useful for solving physics problems with circular symmetry. Here, we derive the calculus and math needed to write F=ma in polar coordinates, which lets us solve problems where forces can act radially and tangentially.

Amazing videos!, Saving fellow undergrads like us who just need a little push in the right direction of math🙌🔥

Beautiful explanation as usual, Sabetta!
We’ve only seen Rigid Bodies so far; however, if I’m not mistaken, your area of research is in soft bodies too.
Wouldn’t it be great to see some videos about Continuum Mechanics/Elasticity Theory/non-Rigid Bodies too? It’s undoubtedly the topic I understood the least in my Undergraduate studies.
You’re great! Keep ‘em coming!

At 2:56 I can't understand how you're using the chain rule. It looks like you're simply using the product rule to obtain the derivative.
