Jump start physics problem with a mass on a spring. This video explains the setup, key assumptions, and the step-by-step physics needed to solve for motion, energy, and forces in a spring–mass system.

In an article published in 2002 in the journal Physics Letters B, my Ph.D. student Maurizio Piai (now Professor of Physics at Swansea University, Swansea, UK) and I proposed an experiment with reactor ...
