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.
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
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 Ugochukwu, This looks like an iron nucleus but I think you gave the radius and separation wrong. I will assume you meant to give me r = 4*10^-15 m. a) The repulsion between those 2 protons
Hello john, Your question indicates some error in your thinking about the meaning of the term medium. But it also seems that your book stretches the truth a little bit. A common example of the term
Hello Rita, I have some problems understanding your question. I used my best guess and rewrote the problem. This is the question I will answer. If I totally misunderstood the problem, feel free to send
Hello trishant, That would be a strange outcome if the bullet doesn't emerge on the path it was on when it was in the barrel. I'm not a student of guns, but I believe the sights are sometimes intentionally
Hello Nathan, In order for the car to follow the circular track, it needs to have centripetal (meaning pointed towards the center) force, Fc, given by Fc = m*v^2/r If you remember Newton's 1st, the
