A chain of mass M and length l hangs vertically with its lower end a height h above a set of scales. In this video we find the mass reading on the scales as a function of time after the chain is released from rest. There are two contributions to the reading: the actual mass of the part of the chain currently on the scales, and the force the chain exerts on the scales as it is brought to rest.
About me: I studied Physics at the University of Cambridge, then stayed on to get a PhD in Astronomy. During my PhD, I also spent four years teaching Physics undergraduates at the university. Now, I'm working as a private tutor, teaching Physics & Maths up to A Level standard.
