that depends. If you are Going down hill then in the air is faster.
Between the undersides of the skis and the snow, and between the air and your body.
Skis for jumping are longer and wider for more air resistence, and skis for racing are long and have slick surfaces and have sharp edges for going faster.
i think that waxing them provides a support on the snow and then creates i guess a ballast upon the snowI think the wax hardens to a ultra-smooth finish filling in the pores of the skis and reducing friction. In a manner of speaking, it is supporting the skis.Waxing skis makes the running surface smoother and reduces friction. This will result in increased speed and smoother running.It does not create a ballast on the snow. A ballast is a tank of something, commonly water or sand, or it is left empty, to alter the buoyancy of a submarine, hot air balloon, dirigible, ship etc in a fluid. Snow is not a fluid. All it does is smooth the bases of the skis and make them slipperier. It makes you go a lot faster. That's it.
Humidity can significantly impact ski performance and snow conditions. High humidity often leads to wetter snow, which can create a heavier, slower skiing experience, while low humidity can result in drier, faster snow. Additionally, moisture in the air can affect the wax on your skis, potentially requiring more frequent waxing to maintain optimal glide. Overall, humidity plays a crucial role in determining snow quality and ski behavior on the slopes.
Skiers reduce friction by waxing the base of their skis, which helps them glide more smoothly over the snow. Additionally, skiers can also adjust their body position and movements to minimize resistance and increase speed. Also, using properly maintained equipment and choosing the right wax for the snow conditions can help reduce friction.
That's true for the airplane's wings, when the airplane is flying upright.
Creating LIFT, This is achieved by causing the air moving faster over the top of the wing in relation to the air beneath the wing.
As earth is moving east to west we should move west to east to faster to our destination.
A snowboard gets more air than average skis unless you have the short skis which can sometimes get more aor but 95% of the time boards get more air
Rain falls faster than snow from the sky because raindrops are larger and heavier than snowflakes, allowing them to fall at a quicker rate. Snowflakes are lighter and can be easily slowed down or carried by wind currents.
The two forces that slow down skiers when going down a hill are friction and air resistance. Friction occurs between the skis and the snow, as well as between the skis and the boots, causing a resistance that reduces the speed. Air resistance is the force exerted by the air on the skier as they move downhill, acting in the opposite direction to the skier's motion and further slowing them down.
Water has a higher thermal conductivity than air, meaning it can transfer heat more efficiently. When in contact with ice, the water molecules transfer their higher heat energy to the ice, causing it to melt faster compared to the slower heat transfer in air.
