Set a camera to free fall like a Rigid Body?

No python needed. Simply add a Copy Location constraint to the camera. Set the Target to an object with an active rigid body. (I simply duplicated one of my colorful cubes and moved it back from the ...

How to make an (open) object behave like rubber when penetrated by another

You could use cloth physics for the deformation part. Pin the corners or edges of the rubber object so it keeps its shape by adding it to a Vertex Group. Let the physics do the rest. Not sure how one ...

Trebuchet Rigid Body

First, apply the Scale and Rotation to all objects (Ctrl+A in Object mode). It's important for the physics simulation. Applying the Location is also a good idea for rigid body simulations. Except here ...

Rigid bodies stick to root

In your scene I see that your domino objects have the origin at the bottom, in physics the origin works as the center of mass so when the origin is down all the weight of the object also goes down. ...

These physics object wont fall straight down

If you are using rigid bodies, you have to understand the concept of convex hull. Convex hull means: your mesh will be simplified as if it would wrapped with plastic. So your ground plane, which shape ...

Physic simulation is visible in viewport, but not in the animation render

You need to cache the physic animation: Go to Scene Properties. Go to Rigid Body World. Under Cache, delete all bakes and then click on Bake All Dynamics. You can now render your video.
