Question

"Science: Why Shoelace Knot Failure"%0D%0Aby Nsikan Akpan%0D%0A%0D%0ATo break down the physics of the phenomena, the researchers attached a small device to the free end of the laces that measured acceleration, and then Gregg went for a walk or a jog. This acceleration creates inertia, which is the tendency for an object to keep moving once it is in motion.%0D%0A%0D%0A“We were surprised that the accelerations were so high. They’re like 7 g [units of acceleration] ,” O’Reilly said. “By way of comparison, the highest g on a roller coaster are 6.3. Your foot is experiencing these really high g-forces as you’re running all the time. It’s a biomechanical miracle that all of that impact is absorbed through your body and spine.”%0D%0A%0D%0AThe knot itself is under pressure too. The videos showed as the shoelaces bounce up and down with each footfall, the main knot begins to deform. Once the knot opens sufficiently, then the free end of the lace, which is being tugged by inertia, begins to slip out.Question, Use the passage from “The Science Behind Why Your Shoelace Knot Is Doomed to Fail” by Nsikan Akpan to answer the question.Which connection is demonstrated by the passage? (1 point)Responses:the impact of acceleration on shoes, the impact of acceleration on shoes, the impact of inertia on the foot, the impact of inertia on the foot, the impact of inertia on knots, the impact of inertia on knots, the impact of acceleration on the spine

Answer 1

The connection demonstrated by the passage is the impact of inertia on knots. The text describes how the inertia of the free end of the shoelace, when subjected to high accelerations, contributes to the formation and eventual failure of the shoelace knot.
