Any physics library for force distribution visualization?

[weijie]

I’m currently finding a library for visualization of force distribution between 2D objects.

Example,
Below is an image of 3 boxes on a trolley.
When the trolley is accelerating to the right, how will the force act from the middle big box on the left smaller box be distributed?

Library? …

I’m currently using Box2d library. Is there any way to visualize the force between objects?
