Love the use of the balloon. Very clever demonstration and clear explanation. Thanks.

This was incredibly well explained- thank you

Although he said it in the video, my teacher always says “the normal reaction (contact force) is not always vertical” all the time because we always assume that it is when it’s.

It's hilarious that my textbook couldn't just explain it like this, instead they decided to only highlight its *significance* without describing it at all.
