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.

You’re going to spend the next few periods analysing your simple pendulum data.  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.
If you are using your chromebook, there may be subtle differences from the Excel instructions I have provided.  Let me know if anything doesn’t work and I’ll try to help.
Note that if you are using your own data, there will be no random uncertainty as measurements were not repeated.

I have attached revision notes from Scholar for the Electromagnetism unit.  Your test will be after the Easter holidays.

You should be thinking about getting some of your project report finished so there is less to do when the deadline approaches.  You can start writing up your underlying physics section and sort out the references you will include at the end of the report.  I’ve attached a guide on referencing in the Vancouver style.  Get back to me if you have any questions.
Thanks to Imperial College London for producing this booklet.

Here are the unit 2 study notes from Scholar that you asked for.  Please do try logging in to Scholar and trying their interactive study materials.

As school is closed today, here are some revision links with you to help with preparation for the unit assessment on Monday.

The link below will give you a copy of the Scholar notes for unit 1.  Log in to your Scholar account to access their tests and check your progress.

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.
