As of right now the speed of his foot with respect to the ice is 7 m/s. As the player additions speed this relative speed changes. For instance‚ on the off chance that he achieves a pace of 5 m/s‚ the relative speed of his foot in respect to the ice is 2 m/s (expecting he moves his leg in reverse‚ with no sideways segment of speed)‚ and the push power is less thus. Thusly‚ there is a greatest pace a hockey player can reach

In 2006‚ he had five speed skaters test out four different older skates and one modern model. One pair of skates was a copy of Bronze Age bone skates.

Explanation 2: This statement helps to relate to the central idea by explaining how the skates have evolved from the earlier bone skates. In his test‚ he explained how it affected the speed with more improvements over the years. The

index measurement is actually a measurement of the speed of light in a medium. The speed of light (usually denoted by c) is 299 792 458 m/s in vacuum. In other media the speed of light is lower than this value‚ and the refractive index‚ R.I.‚ of a medium is a measure of how much the speed of light is reduced in the medium. The refractive index (n) of a medium is defined as the ratio of speed of light in vacuum (c) in to that in the medium (v) The speed of light in a medium depends on the medium itself
