Science 38

Various chains were released from rest with their lower end touching a scale that measured the force, in newtons (N), of the chain on the scale pan. A newton is the force required to accelerate a 1-kilogram mass at a rate of 1.0m/s2 . The mass of the chain, its total length (L), the momentary length of the chain on the pan (x), and the momentary weight of the portion of the chain on the scale pan were also measured. The results are show in in Table 1.
