build a pendulum or newton cradle to experiment with the Vernier photogate and a logger to experiment with the physics behind the pendulum or newtons cradle.
For the pendulum you need
I glued this parts together
further you need
4x steunpilaar_slinger to get the height
you can make the construction higher with 4x verhoging_slinger
The top is formed by
When you make a Newton cradle with 3 balls
4x verbindingsbalk_slinger is replaced by
