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 viscocity and density of the fluid.

The following parameters can be varied within the model:

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.

Windows only.
