Slow Collision Detection

I have a box that applies a velocity to any rigid body that runs into it. While I was looking at a ball colliding into the trigger box
in slow-mo, I’ve noticed that the ball sunk in pretty far before detecting the collision after 2 frames.

Turning the box into a collider kept the ball out of the box better, but it still took 2 frames to detect. Isn’t there a way for the collision to respond faster?

Yes, by changing rigidbody collision detection mode to “Continuous” or “Continuous Dynamic”.
