This unit depends on an ability to explain and understand force extensiona and YM graphs. It is one of the easy topics but also easy to drop marks if you don’t learn the graphs. Also take care of your areas and units as mm don’t convert well to m when you square them for an area calculation!

This video explains how springs behave in parallel and in series for A Level Physics.
If you understand how one spring extends when a load is applied you can then extend ...this knowledge to investigate combinations of springs in parallel and series. This also has many similarities to the way that combinations of capacitors behave when in a circuit.
Thanks for watching,
This video is recommended (although not always mentioned explicitly) for anyone studying A Level Physics in the following exam boards: AQA CIE Edexcel Edexcel IAL Eduqas IB OCR A OCR B WJEC

An elastic band is stretched by hanging a series of 100g masses from it. The band is first of all laden by adding masses. The masses are then removed one ...at a time. A ruler allows measurements to be taken and a hysteresis curve may be plotted. Careful observation will show that the band continues to grow slightly after each mass has been added.

Young's Modulus of Copper - PRACTICAL - A Level Physics

In this video I go through an AQA Physics A Level Required Practical that uses a Young's Modulus experiment to calculate the Young's Modulus of copper wire. (This is AQA ...Required Practical 4.) This is also the OCR A Level Physics PAG 2.1 Practical.
This is a straight-forward way to measure the Young's Modulus of a material. Copper wire is often used as it is stretched by weights hung over the edge of the bench, with the small extension carefully measured with a ruler. Wear eye protection in-case the wire snaps.
