A2 practical: Masses and pulley
In this practical two different masses will be hung on either side of a pulley. Since they are different the bigger one will accelerate downwards. By measuring the size of the masses and their acceleration it is possible to determine g. To measure the acceleration a Smart pulley will be used. This is a pulley incorporating a photo gate. As the spokes of the pulley pass through the gate the time is recorded, the...
