A student asks:
Hi, I am currently doing Mechanics at college and I am finding it very confusing. What can I do to help get my head around the work?
This is another slightly-hard-to-answer question; because I don’t know the student, or what s/he is struggling with, it’s really hard to give concrete advice. However, I’ve seen enough students struggle with M1 to be able to guess! Here’s my reply
Thanks for your message - I can’t give you very detailed advice, but I can make some suggestions about what I know many people struggle with in M1. To get yourself less confused, I recommend:
- Making absolutely sure you know the difference between a force, an acceleration, a velocity, a speed, momentum, and a moment. A huge proportion of M1 errors have their roots in this.
- Drawing big, clear pictures, and getting good at working out which angle is which.
- Shoring up your trigonometry so you can tell when you need a sine and when you need a cosine.
Hopefully there’s something there to help you - good luck!
