For a clear and practical academic paper on the physical pendulum, a highly recommended choice is Pendulums: the Simple and the Physical (arXiv:2308.00603). This paper is particularly useful because it:

: It uses a uniform rod with attached putty to explain how mass distribution affects the period without immediately relying on heavy math.

: It highlights critical locations like the center of percussion and explains why the period remains unchanged at certain pivot points.

: It discusses the existence of a unique minimal period based on the putty's location, which is a classic advanced physics problem. Other Notable Papers by Category Recommended Paper / Source Experimental
