Ice Skating Research Paper
Ever wondered how ice skating works? Why the ice is slippery? Or just how to maintain enough balance to speed up? Well this article will explain why.
Ice skating works because metal skate blades glide with very little friction over a thin layer of water on the ice surface. At one time, scientists thought skaters created the water layer by melting the surface layers of ice through the pressure of their body weight creating a melting point.. However, recent studies disproved that explanation and it is now believed ice is always slippery because the molecules in its top-most layer behave like liquid water.
Ice skating is that it has to do with the pressure of the skate, melting the ice and you skate on the melted water. The phase diagram of the water shows that at 1 atm, the water is solid, but at higher pressures (keeping the temp. the same) the water changes to a liquid.
As mentioned before, ice is very slippery because it has little fraction. The solid surfaces have little bumps and scrapes that can be so small you can’t see them. These are called irregularities. Friction is caused when these irregularities get caught on each other as the two surfaces rub …show more content…
One has to draw their arms and legs towards their bodies. This is related to physical chemistry of the conservation of angular momentum. When a person enters the spin with extended arms, the overall energy of their body has to move their hands and arms in large circles. As they pull their arms in, there is just as much energy as there was before. To conserve energy, the whole body moves faster. In the conservation of momentum, electron spin as well, and if they do it in pairs, they generally cancel out. Unpaired electrons determine the ‘value’ of angular momentum for any given molecule. When energy is pushed into the system, in the form of photons, it is converted into a sort of ‘electronic energy’ - an elevated state of the electrons in the extensions of the
