Forces By Demons (FBDs)

A follow-up to Friction does not oppose motion, for Shruba and the Twisted Mouse:

Forces by demons,
and by engine elves,
and forces of motion
belong on same shelves.

Just two quick questions
you need to ask,
to score full marks
on any forces task:

What am I touching?
(that’s normal and friction)
What g, B, E fields?
all else is FICTION!

I know Shruba doesn’t need a diagram, but there are always marks for diagrams!

  1. There are always marks for diagrams!!! Why am I only learning this now!

    There’s friction with everything I touch? Story of my life.

  2. Aww this is so sweet of you!! Thank you so much πŸ’œπŸ’œ
    I finished my exams yesterday and started reading all the blog posts that I couldn’t read these last few days. Sorry I noticed this so late but thank you ☺☺

    • Congratulations πŸ™‚ Enjoy a break!
      I’ve been marking exams most of the weekend… πŸ˜€
      And did my students listen to me and read the questions carefully?? Did they draw diagrams and write equations when the questions said “explain, using words, diagrams and equations…” No, they did not… 😦 Seriously, most had no equations, and at least half had no diagram!!!

      • Oh no that is a miserable way to spend a weekend. I know our profs are currently burdened by their academic pressure too. This year has been full of peculiar deadlines, can’t even blame anyone. Make sure to take some breaks in between. Hopefully there will be some good papers to check at the end so your spirits gets lifted again. ☺☺

  3. Also, when I was in 11th-12th grade just before my bachelors, I had taken science with PCBM, so yes I cannot stress enough how important diagrams can be sometimes. If you are running short of time but know the core concept and can illustrate it in your diagram, you can still save some marks there! πŸ–€
