How Does the Angle at P1 Change Over Time Until the Object Falls?

[AI_Messiah]

TL;DR Summary

I have provided an illustration so that anyone who understands enough about rigid body physics can understand what I mean.

So I have 2 Points P1 and P2. P2 is the center of mass which has an X and Y coordinate. P1 is where I think that it will fall over from and only has an X location.

Now what I want is to find a way to get how far the angle at P1 will change in relation to where these points are within a given amount of time until the edge on the far right bottom hits the floor and this object may or may not have a velocity when I am making the calculation.

Just calculate the torque from gravity about P1

So as @Dale says, you just sum the moments on your Free Body Diagram (FBD) that you draw for the mechanical system. Do you know how to do that yet? Is this related to your other thread start here at PF?
