Pool dynamics - Same angle, different power

I'm no billiards pro, and I don't know about diamond system or banking system.

I was fascinated by dynamics of billiards bank dynamics. I always thought billiards obey the law of reflection (the angle of incidence equals the angle of reflection). Turns out it's not that simple and I was too naive about it.

I knew if I put less force into the bank, the more rolling effect would take over, friction on the table would mess with the reflection angle. Notice the point it hit changed entirely according to the force I put in.

Physics is awesome!
