Physics Uncovered on Instagram: "Newton’s cradle, with its row of suspended balls, shows how energy and motion transfer from one object to another. When you lift and release one ball, it strikes the others, sending its energy through the line and causing the ball on the opposite end to swing outward. This effect demonstrates the conservation of energy and how momentum moves through connected objects."

Squat University on Instagram: "The science: The resistance band forces abduction (pushing knees outward) and helps maintain hip external rotation, which strongly recruits the glute medius and the upper fibers of the glute maximus (both key players in those actions). This “wakes up” and prioritizes the glutes as the primary hip extensors, reducing the hamstrings’ overcompensation (called synergistic dominance) and shifting neuromuscular control back to the glutes for better activation during the

Knowledge Adaaa on Instagram: "At extreme speeds, centrifugal force pulls the rubber outward, making the tire stretch, expand in diameter, and visibly transform as the rotation grows faster. This effect is magnified by heat from road friction and air pressure inside the tire, which rises with temperature and causes the rubber walls to flex and weaken. Engineers account for these forces by designing tires with precise speed ratings that can withstand pressure, heat, and strain while still maintai
