Mechanical Engineering Thermodynamics - Lec 6, pt 1 of 4: First Law and Baseball

Показать описание
First law applied to throwing a baseball. Note: small error at 10:00 - when evaluating the dot product of two vectors, it is their magnitudes multiplied by the cosine of the angle between the two vectors, not the sine of the angle. Thanks to Alex Sol for pointing this out.

Thanks Alex - you are absolute correct - the dot product always involves the cos of the angle between the two vectors.  Thanks for pointing out the error!  I will add a small note to the video description. - Ron

Thanks Ron. All your Videos are great!
At minute 10: You meant to say "cosine". I know it is irrelevant to the 2nd law point you are making, but maybe a note can avoid confusion.
Thanks again,
Alex
