All of the Year 12 AQA Required Practicals explained - A Level Physics REVISION

Показать описание

This is a summary of all the year 12 AQA required practicals you must carry out for the Practical Endorsement for AQA AS Level and A Level Physics. You need to not only carry these out but also know and understand them, hence why I made video to explain them so it can be used as A Level Physics revision.

I talk through the equipment, measurements and procedures for investigating waves on a string, the double slit experiment and diffraction gratings, determining the gravitational field strength, the Young modulus of a wire, resistivity of a wire and finally the emf and internal resistance of a cell.

To find the video with all the Year 13 practicals, head over to my website at:

Thanks for watching,

Lewis

Thank you SO MUCH. Whole topic videos (if you consider grouping the practicals as a topic) for A-Levels are impossible to find, so I’m really grateful for this.

This is very helpful, please also do the Year 13 one!

is it not v = 2 x gradient for the first practical? this what my school told us?

When you are taking a measurement and say the resolution is 1mm, to what precision do you record to? For example, 98.5cm vs 98.52cm.

Great video thanks. I was just wondering if we also need to know the practical about thermistors?

In CPAC 1 do you have to investigate the effects of all the given variables (length, tension, mass/unit length) on freq., or can you just do one, e.g length?

Nice one. My older son has his A-level tomorrow. I'd have paid your £20 if the subscription were to have lasted until my younger son takes his A-level in 2 and a half years. He'll have to make do with my tuition this evening. We'll subscribe at the start of the next academic year. Nice drawings by the way. Do you actually demonstrate the experiments I.R.L.?
