Investigating a Ski Jump
Background Knowledge: I will use formulas in the prediction to predict
what will happen. The main formulas I will use will be
Loss of potential energy = mgh m=mass g=gravity h=height
Ek =1/2mv² Ek= kinetic energy v=velocity
In the experiment the ball bearing will begin with potential energy.
In order to predict the distance the ball travels I need to find out
the horizontal speed of the ball upon leaving the rail. I will do this
by making Ek equal to mgh to make a new formula, then making it equal
to velocity.
mgh = 1/2mv² gh = 1/2v² v² = ¶2gh
v=¶19.6h h= height started v=velocity g=9.8
This formula will be used to find the horizontal speed of the ball
which in the air will not change as I am ignoring air resistance.
After finding the horizontal speed I will need to find the amount of
time the ball is in air which is the same every time.
S =ut + 1/2at² s = distance u= intial velocity a= accelaration t= time
Aim: To investigate how changing the height a ball is dropped on a
ramp changes the distance it travels.
Prediction: During my prediction I will use these formulas which I
worked out in my background knowledge.
v= ¶19.6h v=velocity h=height
t=¶2s s= distance a= acceleration t= time
a
Vt =distance
In the prediction I can ignore the amount of time it takes to hit the
floor as it will not change.
In the final formulae only velocity will change so it has a direct
correlation. As height is the only variable in the formula velocity
also has a direct correlation.
Therefore I predict that as height of the ball increases distance the
ball travels will increase to.
In the results I will make a graph with height the ball is dropped
from on the axis and the formula ¶19.6h on the x axis and ¶2s
a
on the y. If my prediction is right I should be able to draw a
In lacrosse, the overhead shot is the most vital part of the game and the most important skill that an offensive player can have. The goal of the lacrosse shot is to create a scoring attempt with peak speed and accuracy. Each player is different regarding personal technique; however, the basis of each shot remains the same and are interpreted through six phases. The general purpose of this paper is to describe trunk rotation and its impact on power and accuracy which will maximize the potential of a lacrosse shot.
Cross-country skiing is as much of a competitive sport, as it is a back country one. Cross-country skiing is enjoyed by people of all ages, and can be relatively inexpensive. There is no need for lift tickets and with a little maintenance equipment can last for decades. As a result of its broad audience, many people don't realize that physics plays a large role in cross-country skiing. This web page was designed to briefly describe some of the concepts behind the physics of skiing, and give a basic understanding of both the sport and the science.

At 6pm on a Saturday evening, Sally and her parents were on their way to go skiing for their 20th time. The whole family was extremely excited and looking forward to this, especially since the place was somewhere they’d never been to before. As they were in the car, Sally was daydreaming about what the place would look like, and wondered if her worst fear would be there: ski lifts. Everything about this scared her. The car is out in the open, has no roof, and the ride could malfunction at any time. Since this unanswered question was on her mind now, she decided to ask her parents to see if they knew. “I’m just wondering, do either of you know if there are going to be ski lifts at the place?” Both of her parents paused in confusion but didn’t
In snowboard as in any other sport the athlete has to be thinking at all times, analyzing the situation that surrounds you, make split decisions, and even perform quick calculations in your head.
PREDICTION: I think that the shape with the area of 6 cm2 will have 61
Cascading down frozen mountain, crystallized flakes of chilling water gracing my face with it’s presence; free falling sixty feet, only to be saved by a pillow of snow: this is why I snowboard. The pure rush of adrenaline from the sport has turned what started as a backyard hobby into an Olympic event. Though you may think snowboarding is just a board strapped to your feet; the engineering and history of it have a much richer back story.
One snowy Christmas day in Muskegon, Michigan, a young girl by the name of Wendy Poppen tried to stand up on her sled while sliding down the hill. Seeing this, her father Sherman ran into the garage and bolted a pair of skies together with wood to ""act as foot stops"" (Crane). While watching Wendy use the contraption, some of the local kids ran up to Sherman and asked him to build one for each of them. Little did he know that he had given birth to the “fastest growing winter sport” (Prosl) known as snowboarding. The history, simplicity, and rate of growth of snowboarding took the sport from being completely banned from ski resorts, to being accepted worldwide with its Olympic debut in 1998.
A blanket of white surrounds the men. From atop the high ridge, they spot a lone deer in the distance. The snow inhibits its progression. The men do not need to worry it escaping. Their families will eat well tonight. Using a new invention that they call skis, they quickly overtake the deer. They are able to stay on top of the snow. They quickly slay the deer, and then begin their long trek back to their families. Climbing back over the ridge was no problem, as their skis did not slide backwards, no matter how steep it got. These men did not need to worry about providing food for their families. They could easily cover great distances using long thin wooden planks that became known as skis. Those ancient skis were not like the skis we know. They were much longer and wider, meant for staying on top of the snow. They only used one pole instead of two, the one pole meant for pushing themselves along. They did not use the skis for fun or play. They used the skis for work and transportation. Skis were a great display of ancient ingenuity and inventiveness. Because of those ancient people’s need to move through the snow, skis were created in either Scandinavia or the Atlai region and became an important tool to survive in their winters.
Though my 2015-2016 season ended suddenly, I accomplished multiple things for the short amount of time I had. In the past season’s open races, I was on the podium 3 of the 5 open races I skied in and was top ten in the other two. Though I was unable to attend the Western Region U-16 Championship, I was able to qualify having only completed 6 of the 9 races due to injury. For the 6 races I placed consistently in the top ten with one top 5 and three results just outside of the top ten. Though it was frustrating to not be able to improve as I usually do throughout the season, my almost two months of racing this season were certainly beneficial and aided in my growth as an athlete.
Thin air encompasses me as I commence the final day of skiing at Vail, Colorado. Seven days of skiing elapse rather painlessly; I fall occasionally but an evening in the Jacuzzi soothes my minor aches. Closing time approaches on the final day of our trip as I prepare myself for the final run of the vacation. Fresh off the ski lift, I coast toward the junction of trails on the unoccupied expert face of the mountain. After a moment of thought, I confidently select a narrow trail so steep that only the entrance can be seen from my viewpoint.
In a world that is increasingly affected by pollution, development, and climate change, it is imperative that industries with substantial, adverse environmental impacts make efforts to regulate and minimize them. In this paper, I discuss the alpine skiing industry’s relationship to the alpine ecosystem and the environment as a whole. I use conclusive environmental research to analyze the effects of ski resort development and management on the alpine ecosystem, assess the alpine environment's relationship with climate change, and interpret the role ski resort management plays in protecting and sustaining the environment. I pay specific attention to the effects of grading trails on vegetation and soil, and the consequential impacts on alpine
What type of ski wax will reduce the friction between ski bases and snow the best: rub on, paste, spray on, or hot. Skis slide because when pressure is applied to the snow it creates a thin layer of water in between the ski bases and the snow. Furthermore, skis repel water causing them to slide instead of sticking to the snow. If ski wax is applied by rubbing, pasting, spraying, melting, then melt on wax will reduce the most friction because it coats the skis more evenly, fills in small imperfections and provides a thicker protective barrier.
