I thought it would be fun to see if I could simulate Newton's cradle motion with the Assembly4 (V0.9.3) animator. The following screenshots describe the process:

Extremely impressive (as usual, but still )
Re: V0.19: Just for fun--Newton's Cradle
Love your posts!!
Master sketch, attach to local coordinates, carbon copies, the same words in each post of yours.
It seems that by understanding these few principles, you can use Assembly4 at full power make a lot of things.
Bold of me to ask, but hey : Would it be possible to create a very simplified assembly using these principles, and explaining the thought process in the creation, either with text or with a voice-over? What does what and its purpose, in an ELI5 manner. This would be gold.
Also, I'm not really into the CAD world, but are there (a lot of) things that commercial CAD software can do that FreeCAD can't?

Quite amazing!
Re: V0.19: Just for fun--Newton's Cradle
wow .... impressive, thank-you. In the case of 2 balls bouncing, the motion of the 2 balls is not identical: do you actually calculate the physical laws for the motion ?ppemawm wrote: ↑Fri May 22, 2020 4:45 pm If they can do it in Solidworks we can do it in FreeCAD!...https://www.youtube.com/watch?v=d7QLdHGKtOk

Is this a physics simulation?

Thank you all for the kind comments.

This is only an example to show the potential of using expressions, attachment offset, and the animator. It is the simplest of the simple. There is no physical collision detection other than the conditional statement.
Note that the angle is being incremented by (5) in this simulation. I suspect the delay is caused by the sequential execution of the animator. If you make the increment smaller the delay is less.

No. Pendulum motion is nonlinear. However, the displacement angle as a function of time is approximately related to the cosine of the angle from vertical for small displacements (<20 deg). I am using a sinusoidal change in time to simulate the motion for this demonstration.

I love using expressions and a spreadsheet. It allows me to quickly prototype some more complex model without writing anything in python. Love your work.Keep it up!
