My son Takeh, like most kids, loves slides.
However, despite his good-natured nature, he is quite cautious about things he is experiencing for the first time. He will not get carried away until he assesses the situation.
If it is his first time on a slide, he does not know how much friction and how fast he will go. So he slides on his stomach first to be sure. After repeating this two or three times, he slides on his back. When he fully understood the friction between his buttocks and the slide, he finally slid in a sitting position.
The slide he played that day was made of a single piece of stainless steel. In other words, the kind with a low coefficient of friction that makes it quite slippery.
After a few test runs on his stomach, he finally sat up and started sliding down the slide. However, his style of sliding was to press his buttocks and feet against the sides of the slide and brake with his lower body.
I was impressed. He already understood the physical laws of the world instinctively! I thought.
