Biomechanics of sprint running. Sprinters during a 200 m race. Sprinting involves a quick acceleration phase followed by a velocity maintenance phase. During the initial stage of sprinting, the runners have their upper body tilted forward in order to direct ground reaction forces more horizontally. As they reach their maximum velocity, the ...
Terminal velocity. The downward force of gravity (Fg) equals the restraining force of drag (Fd) plus the buoyancy. The net force on the object is zero, and the result is that the velocity of the object remains constant. Terminal velocity is the maximum speed attainable by an object as it falls through a fluid (air is the most common example).
Step 1: Begin in a seated position with your legs bent. Lean back slightly so your torso and thighs form a V shape, engaging your core to keep your back, shoulders and head lifted. Lift your feet ...
Newton's first law expresses the principle of inertia: the natural behavior of a body is to move in a straight line at constant speed. A body's motion preserves the status quo, but external forces can perturb this. The modern understanding of Newton's first law is that no inertial observer is privileged over any other.
Single-Leg Stand: Stand on one leg while keeping your other leg lifted slightly off the ground. Hold this position for 20 to 30 seconds, then switch legs. For an extra challenge, you can try this ...

The first 13 editions of the Ancient Olympic Games featured only one event—the stadion race, which was a sprinting race from one end of the stadium to the other. [4] The Diaulos (Δίαυλος, "double pipe") was a double-stadion race, c. 400 metres (1,300 feet) , introduced in the 14th Olympiad of the ancient Olympic Games (724 BC).
The following is a glossary of traditional English-language terms used in the three overarching cue sports disciplines: carom billiards referring to the various carom games played on a billiard table without pockets; pool, which denotes a host of games played on a table with six pockets; and snooker, played on a large pocket table, and which has a sport culture unto itself distinct from pool.
