It's the time between the Winter Solstice and Christmas, and the forthcoming New Year... the perfect time to put a bowling ball (attached to the ceiling by cable) to one's chin, let it go, hold REAL still, and see what happens next.

Interested in introductory #physics at the #university level? Check out my lecture playlist from when I taught Physics I (PHYS 1303/1307) at Southern Methodist University. The #lectures each focus on a topic and so can be cherry-picked, etc.

I taught using a flipped classroom model, with peer mentoring and active learning during class.

The physics behind how magnets stop being magnetic when hit by a pulse of light. It's all to do to conservation of angular momentum.
