“This acceleration creates inertia, which is the tendency for an object to keep moving once it is in motion.”
“Your foot is experiencing these really high g-forces as you’re running all the time.”
“The videos showed as the shoelaces bounce up and down with each footfall, the main knot begins to deform.”
“We were surprised that the accelerations were so high.”
“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.”
