What is meant by parabolic?
In mathematics, a parabolic shape refers to a U-shaped curve that is symmetric around an axis. Parabolic structures often exhibit properties like focusing parallel rays of light to a single point (as in parabolic mirrors) or guiding projectiles (as in parabolic trajectories).
Difference between men's and women's alpine skis?
Women's skis have the waist and binding farther forward compared to men's skis to compensate for women's lower centers of gravity and added weight in the rear. Because of lower weights and lower centers of gravity, women's skis also tend to be more flexible for proper turning. Women's skis are also more dramatically curvy than men's skis to make the ski turn better. On straight skis, man or woman, the rule is, "as tall as you or slightly shorter if you're a beginner, a foot taller if you're advanced or just really good." Longer skis can be dangerous, so you need to know what you're doing. On modern shaped or parabolic skis, beginner skis are around chin-height while advanced skiers may have skis up to their forehead or as tall as the skier. Shorter skis are good for beginners as they give more control and better turning. Longer skis get more speed.
Is a parabola the same as a parabolic curve?
No. If you tilt a parabola, you will still have a parabolic curve but it will no longer be a parabola.
What does 'parabolic' mean in mathematics?
Parabolic means that which is expressed by a parable. This word can also be used to describe something that resembles or is part of a parabola or paraboloid. Parabolic has the same meaning as parabolical.
Why antena is in parabolic form?
A: For the same reason a heater is parabolic to reflect heat, For the antenna the opposite is true to focus the incoming waves
How are skis originally made?
One length of wood, thinned out and shaped. Forward end bent upwards.
Do world cup skiers use the same skis as you buy?
Not unless you are a ski racer yourself, and were lucky enough to get top of the line equipment. World Cup skiers get the best race skis that their factory makes. They have many different pairs of the same type (downhill skis, for example) that they will test to see which are the fastest. Race skis are highly specialized and differ greatly from demo skis or skis that the public usually buys. You can see this reflected in the price. Race skis typically run $800-$1000 for the skis, not including bindings.
Why fringes formed due to wedge shaped thin films are straight and not parabolic?
because the thickness of air film is parallel to the edge
Can you replace steel skis on a snowmobile with plastic skis?
Yes, you can just make sure they have the same width and specifications as your old ones.
What materials are used to make the fastest skis?
All skis are usually made of wood, so depending on the type of wood the lighter and the faster the ski will be. The way the ski is also shaped also help with the speed as well.

What are carving skis?
Before 1990, skis typically had straight parallel edges, i.e. the same width everywhere. Then came along the snowboard, which was able to "carve" easily due to the curved siderails, which made the board narrowest in the middle. This shape made the snowboard easy to turn by tilting it on its edge, and riding this way became known as "carving". To allow skiers to carve with the same ease as snowboarders, the skis were modified to have a shape similar to snowboards: Wide at the ends, and with a narrow width in the middle of these skis. At their introduction, such skis were sold as "carving skis", to differentiate them from the traditional, straight-edge skis. The "carving skis" were indeed easier to turn and learn. They became a big success and generally replaced the older ski design. As a result, today pretty much all skis are "carving skis", and the distinction is not really necessary anymore. SJO
