In Botsingen or 'Collisions',
various aspects of motion, momentum and kinetic energy are explained.
This is done using a graphic representation of one or two balls that
collide with walls or each other in various ways. The simulation
gradually builds up from analysing simple unanimous motion (x,t-diagrams,
v,t-diagrams and a,t-diagrams are explained) to analysing different
types of collisions:
- Collisions with a
- Elastic collisions
contains a lot of different assignments (50 or more) in four
different contexts, each with full feedback. There is a clear,
gradual build-up between contexts, and also within every context as
such. This simulation, or elements from it, is a real addition to
every dynamics course.
