On Vacation
returns 12/10/2016

I would be delighted to help with questions up through the first year of college Physics. Particularly Electricity, Electronics and Newtonian Mechanics (motion, acceleration etc.). I decline questions on relativity and Atomic Physics. I also could discuss the Space Shuttle and space flight in general.

Experience in the area

I have a BS in Physics and an MS in Electrical Engineering. I am retired now. My professional career was in Electrical Engineering with considerable time spent working with accelerometers, gyroscopes and flight dynamics (Physics related topics) while working on the Space Shuttle. I gave formal classroom lessons to technical co-workers periodically over a several year period.


BS Physics, North Dakota State University
MS Electrical Engineering, North Dakota State University

What do you like about this subject?

I went into Physics because it was the first material I both liked and understood in high school. I did well in my first year of college Physics, but the later years required higher math than my comfort level so after earning my BS degree in Physics, I switched into Engineering for my MS degree.

Hello Tess and Madelaine,    Yes there are forces in this scenario. Of course there is the force that is applied to the stick that makes it fly. And there is the stick's weight. Both of those act downwards

Hello Heather,    There have been many questions on allexperts about egg drop projects. The Search feature at top right on this page would -previously- work well to generate a list of them. That would

Hello Ankit,    Since none of the options have a minus sign, I guess we ignore polarity since in i and iii, B would go in opposite directions. Other than direction, i and iii are very similar. By the principle

2016-11-13 Tipcat experiment:

Hello Tess and Madelaine,    To help you understand the principles, I suggest introductory experiments hitting a stick. Use a uniform stick about 1/3 m in length. (If you were in North America, I would
