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
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
Use the attached file to help with revision for your test on Monday. Start at the beginning of the booklet and read up to the end of page 41. Thanks to Mr Noble for sharing his notes. 🙂
//www.youtube.com/watch?v=QK5Bxf3Pov0 We’ve been looking at work and the rate of change of energy. This handout will help you to revise the key points and introduces gravitational potential energy.
Your homework questions are attached. Please return to me by Wednesday 20th September.
Today we examined the importance of Newton’s 3rd law of motion. In our discussions, different explanations for the motion of jets and rockets were proposed and considered. The front runners were; at launch, the ground pushes back against a rocket during flight, air pushes back against a plane Unfortunately, the lack of ground and air (or ... Read more
Here are some notes to help you prepare for the assessment later this week. There are also some useful resources on BBC Bitesize.
The period (T) of a simple pendulum can be calculated using where l is the pendulum length and g is the gravitational field strength. Using a single value of length and period, we can determine the acceleration due to gravity. However, it would be better experimental practise to vary the length of the pendulum and ... Read more
Here are whole unit summary notes to help you prepare for the unit test next week. Thanks to Mr Noble for sharing his notes.
Here are some revision notes on waves to help you prepare for the unit 3 test next week.
