WebWearing a swim cap or having a shaved head is another way to minimize both friction and pressure drag. The degree of drag reduction you can achieve depends on many factors, … WebExplore the mechanics of the lungs and rib and diaphragm muscles involved in human respiration. Alveolar pressure fluctuations are caused by expansion and contraction of the lungs resulting from tensing and relaxing of the muscles of the chest and abdomen. Each small increment of expansion transiently increases the space enclosing lung air.

WebThe earliest strokes to be used were the sidestroke and the breaststroke. The sidestroke was originally used with both arms submerged. That practice was modified toward the end of the 19th century by bringing forward first one arm above the water, then the other, and then each in turn. The sidestroke was supplanted in competitive swimming by the crawl (see … WebOne takes off with an acceleration of 1m/s/s and the other takes off with an acceleration of 1.5m/s/s. 1. F = 80kg x 1m/s/s. F = 80N. 2. F = 80kg x 1.5m/s/s. F = 120N. - If force is increased, then acceleration increases when mass is constant. - If mass is increased, then force increases when acceleration is constant.
