Final answer:
Catching a ball with a 'give' demonstrates the preferred method of entering water with less impact and resistance, similar to a proper dive in swimming. Hitting the water with the full palm represents a belly flop, which is advised against due to discomfort and inefficiency. A gradual entry with fingers first illustrates the effectiveness of reducing resistance and a smoother transition into the water.
Step-by-step explanation:
The procedure mentioned is related to understanding the effects of different techniques when interacting with water, which is a part of learning about water safety and swimming techniques.
When you catch a ball and give with the ball, pulling your hands toward your body, you are effectively absorbing the impact, which is similar to a swimmer entering the water with a proper dive, minimizing resistance and discomfort. This is the preferred method in swimming as it leads to a smoother entry into the water.
Catching a ball without moving your hands causes a harder impact, akin to a belly flop in swimming. This is less comfortable since there is more resistance upon impact. This illustrates why a belly flop, represented by hitting the water with your full palm, is not advised because it can be painful and less efficient for moving through water.
Hitting water with your fingers first, in contrast to with your full palm, demonstrates how entering the water gradually (like in a streamlined dive) minimizes resistance and is more effective for swimming. This action disrupts the water less, reducing splash and allowing for a faster, sweeter entry. Therefore, people should be advised to avoid belly flops due to increased impact and resistance which can be harsh on the body.
