"Which of Newton's Laws (First, Second or Third) says that an object will move in a straight line at a constant speed without a net force? This is a terrible question for the following reasons: Does it really matter which law is First, Second, and Third? Technically, both the First and Second Law would be correct answers. It misses the main point about forces and motion and instead gives some type of recall-based question. I just think we can do better. Just because most physics textbooks (but not all) have been very explicit about Newton's Laws of Motion, this doesn't mean that is the best way for students to learn."

Interesting to think about using 3D body motion tracking to paint and create animation. It's a fun mix of real world movement and software.

I don't think this is cognitive bias but it's interesting.
