Question
science: why shoelace knot failure by nsikan akpan to 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. \we were surprised that the accelerations were so high. theyre like 7 g units of acceleration,\ oreilly 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 youre running all the time. its a biomechanical miracle that all of that impact is absorbed through your body and spine.\ use the passage from science: why your shoelace knot is doomed to fail by nsikan akpan to answer the question. connection: the g - forces put pressure on the knots in the same way they put pressure on the body and spine. which pieces of evidence support the connection? select the two correct answers. (1 point) \your foot is experiencing these really high g - forces as youre running all the time.\ \to 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.\
The first option directly mentions the high g - forces experienced by the foot while running, which relates to the connection about g - forces on the body and spine. The second option describes the experiment of measuring acceleration on the shoelaces when a person walks or jogs, showing how the g - forces are generated and measured, thus supporting the connection.
