How does change in pressure help in ice skating?
When ice skating, applying pressure on the ice with the blade of the skate helps create friction between the blade and the ice, allowing the skater to push off and glide smoothly. By adjusting the pressure applied to the skate, a skater can control their speed, direction, and stability on the ice. Changes in pressure also help to initiate turns and maneuvers while skating.
Why do you skate faster on ice than on the street?
Skating on ice reduces friction as the skate blade glides more smoothly over the surface compared to the rougher pavement on the street. This lower friction allows for faster acceleration and higher speeds on the ice. Additionally, the lack of air resistance on ice contributes to the ability to skate faster compared to on the street.
Jiffy ice augers why does your auger bind?
Jiffy ice augers can bind due to several reasons, including ice buildup on the blades, dull blades, or a misaligned blade. Regular maintenance, such as keeping the blades sharp and clear of ice, can help prevent binding issues. If the auger continues to bind, it may be best to have it inspected by a professional to identify the specific cause.
An ice skater slides at a speed of 25 km per hr on a level ice track At this point she allows herself to coast to a complete stop How far will the person coast?

High pressure under skaters shoes lowers melting point of ice explain?
Under the pressure exerted by skates, the melting point of ice decreases due to the compression of the ice crystals. When pressure is applied, the ice molecules become more tightly packed together, causing a decrease in the amount of energy required for the molecules to transition from a solid to a liquid phase. This is why the pressure from skate blades can lead to the melting of ice beneath them, allowing for smooth gliding.
