This software models the passing of a voltage through metal wires of varying dimensions to see how resistance and current varies until a power equilibrium is reached, when the power going into the circuit equals the power coming out via heat emission. It is designed to support the teaching of Science and Physics at GCSE and A Level. The model takes into account the resistivity and temperature coefficient of the metal. The following parameters can be varied within the model: Voltage applied; Length and diameter of the wire; Room temperature; The required sample interval. As these parameters are varied, the number of samples that will be taken is displayed so that the optimum number for a particular experiment can be selected. The temperature, resistance, power in and out and current are calculated for each sample. Parameters can be adjusted and the metals list modified to the user’s specification. These new settings can be saved in a file for later use. The results can be printed and also exported as a CSV file for further analysis or graphing. The application is supported by a comprehensive help file which includes guidance on how to generate the required number of samples.

This software contains two models: The Fundamental Frequency Of A String Or Wire Under Tension This software calculates the Fundamental Frequency of a string or wire under tension and plays a tone at that frequency. It is designed to support the teaching of Science and Physics at GCSE and A Level. The model takes into account the density of the material. The following parameters can be varied within the model: Length of the string or wire; Diameter of the string or wire; Tension the string or wire is under. The volume and mass of the string or wire are calculated as well as the Fundamental Frequency. Parameters can be adjusted and the materials list modified to the user’s specification. These new settings can be saved in a file for later use. The results are calculated in real time as the parameters are changed, and can be printed. A tone can be played at the currently calculated Fundamental Frequency if it is within the system boundaries. The Fundamental Frequency Of A Gas Filled Tube Or Pipe This software calculates the Fundamental Frequency of a gas filled tube or pipe and plays a tone at that frequency. It is designed to support the teaching of Science and Physics at GCSE and A Level. The model takes into account the Heat Capacity Ratio and the Molecular Mass of the gas. The following parameters can be varied within the model: Length of the tube or pipe; Temperature within the tube or pipe; Whether or not the tube or pipe has one end closed. The speed of sound is calculated as well as the Fundamental Frequency. Parameters can be adjusted and the gases list modified to the user’s specification. These new settings can be saved in a file for later use. The results are calculated in real time as the parameters are changed, and can be printed. A tone can be played at the currently calculated Fundamental Frequency if it is within the system boundaries. The application is supported by a comprehensive help file.

This software models the heating of liquids in an insulated container over time and is designed to support the teaching of Science and Physics at GCSE and A Level. The model takes into account the density, boiling point and specific heat capacity of the liquid. The following parameters can be varied within the model: Mass and initial temperature of the liquid; Room temperature; Resistance and current of the heater; Heating time; Container diameter and insulation thickness; The required sample interval. As these parameters are varied, the number of samples that will be taken is displayed so that the optimum number for a particular experiment can be selected. The energy used, liquid temperature and the temperature rise are calculated for each sample. Parameters can be adjusted and the liquids list modified to the user’s specification. These new settings can be saved in a file for later use. The results can be printed and also exported as a CSV file for further analysis or graphing. The application is supported by a comprehensive help file which includes guidance on how to generate the required number of samples.

This software models spheres falling through different fluids. It also models their rising after bouncing, should they bounce. It is designed to support the teaching of Science and Physics at GCSE and A Level. The model takes into account the viscosity and density of the fluid. The following parameters can be varied within the model: Height from which the sphere falls; Mass and diameter of the sphere; Energy loss on impact; The required sample interval. As these parameters are varied, the number of samples that will be taken is displayed so that the optimum number for a particular experiment can be selected. The fall time, fall velocity and fall distance are calculated for each sample as the object falls. The rise time, rise velocity and rise distance are calculated for each sample as the object rises. If the object instead floats in the fluid when released, then this is reported. Parameters can be adjusted and the fluids list modified to the user’s specification. These new settings can be saved in a file for later use. The results can be printed and also exported as a CSV file for further analysis or graphing. The application is supported by a comprehensive help file which includes guidance on how to generate the required number of samples.
