A2 practical: Newton's second law support
To learn how to deal with uncertainties when multiplying by a constant. This practical uses a standard dynamics trolley and track. I use the 2m track which gives a bit more space to work with. The Pasco trolleys have a mass of about 500g which gives reasonable acceleration for masses between 10g and 50g. A standard pulley is clamped to the end of the bench so that the string runs freely.
