introducing special relativity…⤴

from @ fizzics

We’ve been looking at Einstein’s special theory of relativity this week.  Special relativity is tricky get get your head round.  Let’s start with a video about the speed of light. We watched this video in class, it follows Einstein’s thought process as he worked through his special theory of relativity. special relativity from mr mackenzie on ... Read more

H tension HW answers⤴

from @ fizzics

I’ve marked your HW jotters and will hand them back during tomorrow’s lesson. I’ll go over the main issues in class but many of you need to review the way you attempt tension questions; use a free body diagram and only use F=ma when you know the resultant force.  These two videos should help. HW ... Read more

higher assignment⤴

from @ fizzics

Your assignment will be based on an optoelectronics topic.  You will get some ideas for practical work by downloading this booklet. I have attached a copy of the Scholar notes for unit 3 of the CfE Higher course.  You will find background physics with appropriate energy band explanations on pages 103-142. Don’t print this document, ... Read more

particle accelerators⤴

from @ fizzics

An electric field can be used to accelerate charged particles. Conservation of energy tells us that work done by the electric field = change in the particle’s kinetic energy The speed of the particle can be determined if its charge and the accelerating voltage (potential difference) are known.  The notes attached to the end of this post ...
