## nat4 dynamics & space revision – post #2

Here is the second set of revision notes for your test.

## nat4 dynamics and space revision notes

This is the first of two posts with summary notes to help you prepare for the unit assessment next week. Don’t forget that there are also nice notes with built-in tests on BBC Bitesize.

## nat5 revision

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. 🙂

## nat5 – work, power and potential energy

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.

## higher homework

Your homework questions are attached. Please return to me by Wednesday 20th September.

## higher ODU revision notes

Here are some notes to help you prepare for the assessment later this week. There are also some useful resources on BBC Bitesize.

## using Excel’s LINEST function

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 plot a graph of against length, determining g from the gradient of the line of best fit.

We’re going to spend the next three periods analysing your simple pendulum data in the library. The attached pdf will walk you through the steps. It would be better if you used your own results but I’ve put some sample data on the first page if you’ve forgotten to bring yours.

## nat5 – waves and radiation summary notes

Here are whole unit summary notes to help you prepare for the unit test next week.

Thanks to Mr Noble for sharing his notes.

## national 5 electricity and energy revision notes

Here are some notes to help with your revision for the electricity & energy test.

Thanks to Mr Noble for sharing his notes.

There are also practice exam questions and answers if you want them.
