A captivated audience watches the dizzying spins of gymnasts, the powerful glides of top swimmers, and the goal-scoring kicks of soccer players. The Summer Olympics have started! But there's more than speed and skill involved in the athletes' medal-worthy performances. Science plays a role in each well-rehearsed movement, in top speeds, and even in the protective gear used in the Olympics. Go behind the scenes to have a close look at how science is involved in your favorite Summer Olympic sports, including gymnastics, swimming, track and field, and soccer. Behind the flips, splashes, and speed of Olympic water sports, science is at work. Gravity and angular momentum are in play as a diver spins and flips before splashing into the water. Olympic swimmers wear high-tech swimsuits to reduce drag as they zip through the water, hind out how science is involved in all your favorite water events and how athletes take science into account in their quest for the gold medal.
