Im Kreis fahren
About points...
We associate a certain number of points with each exercise.
When you click an exercise into a collection, this number will be taken as points for the exercise, kind of "by default".
But once the exercise is on the collection, you can edit the number of points for the exercise in the collection independently, without any effect on "points by default" as represented by the number here.
That being said... How many "default points" should you associate with an exercise upon creation?
As with difficulty, there is no straight forward and generally accepted way.
But as a guideline, we tend to give as many points by default as there are mathematical steps to do in the exercise.
Again, very vague... But the number should kind of represent the "work" required.

We associate a certain difficulty with each exercise.

But once the exercise is on the collection, you can edit its difficulty in the collection independently, without any effect on the "difficulty by default" here.
Why we use chess pieces? Well... we like chess, we like playing around with \(\LaTeX\)-fonts, we wanted symbols that need less space than six stars in a table-column... But in your layouts, you are of course free to indicate the difficulty of the exercise the way you want.
That being said... How "difficult" is an exercise? It depends on many factors, like what was being taught etc.
In physics exercises, we try to follow this pattern:
Level 1 - One formula (one you would find in a reference book) is enough to solve the exercise. Example exercise
Level 2 - Two formulas are needed, it's possible to compute an "in-between" solution, i.e. no algebraic equation needed. Example exercise
Level 3 - "Chain-computations" like on level 2, but 3+ calculations. Still, no equations, i.e. you are not forced to solve it in an algebraic manner. Example exercise
Level 4 - Exercise needs to be solved by algebraic equations, not possible to calculate numerical "in-between" results. Example exercise
Level 5 -
Level 6 -

The following quantities appear in the problem:
Masse \(m\) / Kraft \(F\) / Geschwindigkeit \(v\) / Ortsfaktor \(g\) / Radius \(r\) / Winkelgeschwindigkeit / Kreisfrequenz \(\omega\) / Reibungskoeffizient \(\mu_{\rm Gl,H}\) /
The following formulas must be used to solve the exercise:
\(F = mg \quad \) \(F_R = \mu F_\bot \quad \) \(F = m\dfrac{v^2}{r} \quad \) \(F = mr\omega^2 \quad \)

Exercise:
Ein Wagen fahre auf einer horizontalen Strasse im Kreis wobei der Kreisradius m betrage die Haftreibungszahl sei .. Wie schnell kann der Wagen fahren ohne seitlich wegzurutschen?
Solution:
In vertikaler Richtung bewegt sich der Wagen nicht d.h. F_resy myRarrow F_N F_g. In horizontaler Richtung wirkt lediglich die Haftreibung damit erhalten wir: F_rexx ma_z myRarrow mu_Hmg ma_Z myRarrow v sqrtmu_Hgr apx .
