Throughout this experiment, hot wax has displayed that it is able to reduce the friction between the ski bases and the snow quicker than any other material used. Over the time line of this experiment nearly all of the ski waxes enhanced the speed of a skier. Overall, the materials used continued to display consistent results in comparison to each other. Each time, hot wax demonstrated the quickest speed followed by rub on, paste, and spray on wax. Prolonged quality was evident with the hot wax and was more efficient in general. Hot wax proved superior to quick wax in coating ability (Website 2). Rub on was applied directly to the ski on and then polished with a cork (Website 3). The paste wax is also known as a glide wax. “Glide” waxes – promote smooth movement and allow the base of your ski to slide along the snow at a high-speed rate (Website 3). Spray on and paste waxes are typically used as a top coat to hot wax to further improve the performance of a skier. These waxes are fast and easy to apply and last for a day of skiing or less (Website 5). Because spray on wax is traditionally used as a top coat it was not as resourceful when used on its own in two out of three …show more content…
Using a stop watch could give a broad idea of which wax is able to reduce friction the best. The time in the data were tenths of seconds from each other, paste wax could have been faster than rub on if timed inaccurately. Stop watches will never be an exact time of what occurred. Human are know for making mistakes, so inaccurate time could have been a dilemma. Time sensory experiment would get the exact time it would take the ice disc slide down the ski. Due to the cost of this specialty equipment a stop watch was used instead. The next step to further investigate is to research different brands and repeat this experiment the same way with new
Chapter 1 of Part 3 titled, “Insertion”, in The Hot Zone by Richard Preston Jerry Jaax wakes up in the morning and gets ready. All of his team wore civilian clothing, because wearing space suits would panic the media. He leaves the house and arrives at the Institute. Whole crowds of people were waiting at the side of the building. He spotted Gene Johnson, he was pacing back and forth across the loading dock. There were many camouflage military trunks that contained Johnson’s gear from Kitum Cave. A white van pulled up and Johnson loaded his equipment into it. This van was headed to Reston. By now, The Washington Post newspaper had a headline on their paper saying that a deadly Ebola virus was found at the monkey house. Top-level workers were
In his book, The Hot Zone, Richard Preston focuses on an outbreak of the Ebola virus in Reston, Virginia and in multiple places in Africa. To show how dangerous an outbreak can be, Preston examines, in great detail, various other viral outbreaks, including Marburg. Preston begins by talking about a fifty-six year old Frenchman named Charles Monet who ends up breaking out with a treacherous disease called Marburg. This wasn’t known until his doctor, Dr. Shem Musoke, ended up testing positive for Marburg after Monet`s infected blood went all over Doctor Musoke as Monet was dying. Musoke survived his outbreak with Marburg.
High Heat by Carl Graduating High School is a must yet going to college is a plus. High Heat by Carl Deuker, Shane was always on the straight road to life. His parents had him on a good path and also a good head on his shoulders. They had their kids in the best of schools living in a upper class neighborhood. When one day at his baseball games his father was arrested on money laundering, that’s when he lost everything.
4.1 “What a Drag” lab tested 5 different surface areas; Tabletop, Waxed paper, Paper towel, Fine sandpaper,and Coarse sandpaper. These 5 different surface areas caused the weight to appear different . The data shows that it increases each time you do it again. Each time you pull the block over the 5 different surfaces it can increase or decrease.
I chose this method to keep the two Ice cubes separated during the experiment, and to see the two individual results of adding salt, or adding nothing to the ice. Keeping the Ice cubes separate allows no error in collecting data on each individual subject. Adding salt to one will not interfere with data collected on the ice cube melting with no additives. Some studies were very similar, but most used many different substances to test how quickly Ice would melt. These included for instance Sugar, and Sand.
Over spring break I had the great privilege of going to the Nation Blacks In Wax Museum in Baltimore Maryland. The Black In Wax Museum was founded and designed to teach people the history of African Americans from the Middle Passage to current events. The Museum is one of the most dynamic and cultural institutions because not only is it solely dedicated to the preservation of African American history, but the life-like wax figure gives it its’ uniqueness and creativity.
The coefficient of kinetic friction, or the μk, is equal to FF/FN while the materials are in motion, sliding across the other surface. In this case, the FF on each object is exerted in the direction opposite to the direction of its motion. The values of μk vary greatly between different combinations of objects. Most dry materials have values of μk between .3 and .6, and in some rare cases values as low as .04. Wet materials have even more varied values of μk – for example, waxed wood on wet snow has a μk of .1, while ice on ice has a μk of .03, and joints inside of the human body, which have very little friction as they move against each other, have values of μk around .003.
The day of the 5th grade wax museum of the 2012-2013 school year at Polenta Elementary. It was spring, but the temperature outside was in the 80s. I was playing as Paul Revere which I was the only girl to do so. When other kids would come and press the button on my hand I would speak my lines that I had learned to say from the research I had done. I sat between Pocahontas and JFK, two figures that weren't even in the same time period as Paul Revere had been.
Purpose: The purpose of this experiment is to observe the temperature of ice and water during the constant addition of heat. Also, to use logger pro probes and software to collect and analyze the data. Lastly, observe graphically the temperature data as the ice melts, water warms then boils.
For more than two decades Kinderlift of Colorado in Denver has been the go-to source for kids’ ski equipment for ski schools and ski resorts the world over.

So all this month shop directly on the Kinderlift website for kids' ski clothing, including the popular Children’s Safety Ski Vest. Because as every parent knows, fun and safety should go hand in hand.
This quality assurance was best displayed through Howard Head’s statement that attention to detail is what separates Head Ski from their competitors and that even during tough financial times, any defects or quality deviants were recalled without hesitation. Furthermore, the design of the ski is crucial to the performance of the skier and needs to take into consideration the 3 core functions of: Tracking, Traversing and Turning. Although in the early years as per Mr. Head, the main concentration was to make the best ski for the general public, by 1966, Head Ski was the top choice for performance for both, unskilled beginners and the top professional racers. This advantage in performance was prominent in a major international competition where one-third of all top 10 finishers were using Head products. Additionally, Head Ski truly believed in functionality before style. While competitors often introduced 6-8 different colours yearly for their skis, Head stuck to the basic colour of black and rarely made any model changes unless performance was lacking. The simplicity of using one colour really made Head distinctive and unique on the slopes and ultimately creating a status symbol for the brand. The emphasis on selective dealer relationships was a very strategic and distinctive strategy by Head. Many large stores were declined the opportunity to
Snowboarding has reached a height in popularity that has some didn’t think was possible. The snow boring industry has grown by a tenfold by now grossing 5 billion dollars a year. Many companies have invested millions of dollars into
Nordic skiing, also known as cross country skiing, has popularized over the previous decades. This sport involves several muscles working together to achieve the fastest speed while maintaining the speed for the entire race. This sport is very difficult and requires full commitment to be successful.
The physics of skiing and snowboarding are very similar. They both rely on a downwards pull from gravity. This pull is what turns the potential energy into kinetic energy. As a smooth surface (or two) pass over the snow a small amount of energy is lost to friction. The bottom of the skis or board zoom across the surface of the snow creating heat. The heat along with the weight bearing down on the snow melt some of the snow creating a film of water on the bottom of the surface. Some energy is also lost by through wind resistance of the riders silhouette.
Located to the northwest of Los Angeles, Hollywood is known as a center of film history representing the entertainment and film industry of United State. The Hollywood Boulevard is also a home of many movie stars who are famous all over the world and supported by lots of fans. To satisfy the fans’ dream of seeing their idols in person, in 1965 the Hollywood Wax Museum was built and made up with the wax figures featuring the replicas of celebrities.
