Assessment
Optional Practical: Variable power heater
In this practical a fixed mass of water will be heated with a 12V electric water heater connected to a variable power supply. By measuring the power supplied to the water and the rate of change of temperature...
Assessment
Optional Practical: Uniform electric field
In this practical the the electric field between two parallel plates will be investigated using conducting paper. Set up the electrodes as in the photo below. It is best to use the side of paper without...
Assessment
Optional Practical: The conical pendulum
A conical pendulum is a pendulum that is spun round in a circle instead of swung backwards and forwards. In this experiment a mass is attached to a string and made to spin in a circle of fixed radius,...
Assessment
Optional Practical: Standing waves in a slinky
In this experiment a transverse standing wave will be set up in a length of slinky spring and its time period measured with a stop watch. If we treat the spring as a thick string then the velocity of...
Assessment
Optional Practical: Spinning stopper
In this practical you are going to spin a rubber stopper on the end of a string. The string is passed through a tube and mass is attached to the other end (as in the diagram below), this will provide...
Assessment
Optional Practical: Sliding whistle
In this practical the frequency of the note from a slide whistle (bought from Ebay) will be measured using the programme Audacity, this is a free programme that can be downloaded from http://audacity.sourceforge.net/...
Assessment
Optional Practical: Skipping rope
When a rope is used as a skipping rope it forms a shape the same as the shape of the first harmonic of a guitar string. Unlike a guitar string this pattern can be formed at any frequency. In this experiment...
Assessment
Optional Practical: Resonance in a bucket
In this practical water waves in a shallow rectangular container will be investigated. Pour about 1cm depth of water into the container and place it on the table. Push the side of the container and you...
