Physics: I want to achieve a high force with a low speed. How is it possible?

I am looking to create a physics based elevator. I want it to be able to lift both light weight objects and heavy ones. I want this elevator to always have the same speed.

Notice that simply clamping the rigidbody speed doesn’t work, I get weird behavior. Does anyone have any other tips?

Good day. You are trying to control the speed by adding forces, its not recommended at all. If want to make an elevator, maybe you should move it by other commands like Translate() to control the speed.
