This collisions simulation is by Phet. Click on the advanced tap to get collisions at different angles.
This is a core practical for Edexcel A level Physics. This simulation can be used alongside the actual practical which can be difficult to set up and get decent results from, but should be attempted.
Core practical 10: Use ICT to analyse collisions between small spheres
The aims of this practical are:
To investigate the conservation of momentum in two dimensions
To determine whether a collision is elastic
The simulation can help with core skill 11 – to use ICT such as computer modelling
