Investigation looking At the Speed of Reactions Introduction The aim of this experiment is to find out how a variable can affect the results from a scenario set up in scientific environment. The experiment is to see how a certain variable will affect the amount of Gas produced from a Calcium Carbonate and Hydrochloric Acid Reaction. The Science Calcium Carbonate is a generally white or colourless mineral that is translucent. When compressed or exposed to great heat the mineral binds together
Speed of Dissolving Jelly Introduction The investigation I have to do is I have to investigate what affects the speed at which the jelly will dissolve in water. This investigation will be using the theories we have covered on the rates of reaction and the collison theory. I am going to try to get the jelly to dissolve quicker by increasing the surface area. I predit that when increasing the surface area
Factors that Affect the Speeds of Rollercoasters AIM === The aim of this investigation is to find out how one chosen factor affects the speed of a roller coaster car at the bottom of a slope. In the investigation, a marble is used to represent a car. ---------------------------------------------------------------------- FACTORS ------- VERTICAL HEIGHT OF SLOPE (THE HIGHER, THE FASTER) ------------------------------------------------- GRADIENT OF THE SLOPE (THE STEEPER
Speed Kills The high speed limits are often causes of accidents that cause serious injuries and even death. The speed limit should be lowered so we can control accidents caused by high speed driving, pollution, and the high cost of operation and insurance. First of all it is obvious that a motorist driving over the speed limit has more chances of getting into an accident that a motorist who is traveling at the average speed. One who drives fast does not have proper and that well of a control on the
This lab experiment was conducted in order to test the speed of sound, which is the distance traveled per unit time by a sound wave. This experiment was carried out with a certain setup, which involved materials such as a computer, a Logger Pro, a vernier microphone, two tubes, a temperature probe, a meter stick, and a dog trainer clicker. These materials were set up in a specific fashion, the Logger Pro was connected to the computer, which allowed for a temperature reading. The microphone was then
High Speed Pursuit: To Chase or Not to Chase? Since the origin of crime, criminals have attempted to evade justice. This is evident when criminals tamper with evidence, take hostages, and attempt to flee the scene. With the introduction of the automobile, fleeing the crime scene has become dramatically simpler. As technology increases, these automobiles are safer, handle better, and go faster than ever before. The police therefore are forced into pursuit with their own automobiles, endangering
The Speed of Light Through Perspex Planning Light travels at different speeds through different mediums. The speed of light in air is 300,000,000m/s. When light enters an optically denser medium, it bends towards the normal (refracts). You can work out the refractive index of by dividing the sine of the incidence angle by the sine of the angle of refraction and then working out the ratio of the two. Sine i Sine r From this refractive index you can work out the speed of light through
will investigate the properties of mechanical waves such as a longitudinal wave, focusing on the question: Does a change in the frequency of a wave result in a significant and convincing change in the speed of the wave? Hypothesis: Changing the frequency of the wave will not result in a change in speed because the wavelength will change proportionally as in theory. Student Designed Investigation Procedure/ Planning Procedure: 1. Three students would get into a group. 2. A Slinky would be
Have you ever wanted to drive faster without being pulled over for speeding? Of course you have, we’re America it’s what we do, we go fast! This is just one of the many reasons on why we should raise the speed limit. We should raise them not only on highways, but also on interstate. I believe that highways should be raised to 60 or 65 mph, and interstate should be raised to 75 or possibly 80 mph. One reason is, that drivers are always complaining about getting stuck behind slower drivers. This problem
Output, input, Storage and Speed of the Computer Printed questionnaires Intelligent Character Recognition (ICR) would be the best choice. Its the ICR technology that allows data capture software to automatically to, read information from all types of documents - even handwritten ones. Telephone survey-voice recognition is best because a voice input device can be programmed to distinguish answers spoken into the receiver allowing it to all be completed by computers. Bank checks- scanning devices
that anyone can enjoy irrespective of race, nationality, creed or how you might feel about muffins? Consider yourself told. When news slip that Criterion was developing the next installment in the 16-year-old and perpetually estranged Need for Speed franchise, it sparked more than just expectations. It created almost insurmountable hopes and dreams. To show us how they plan to surmount those hopes and dreams, is Craig Sullivan. He's the Creative Director on Hot Pursuit 3 (not it's real title,
recent years. That includes trying to increase the speed of the cars at whatever means possible. The IRL was formed a few years ago under the direction of Tony George. He is trying to make the sport less expensive and safer by using different motors/chassis and slowing down speeds. Racing has always been about going faster than the next driver. It was about trying to beat course records and lap speeds. But if Tony George has his way, all course speeds will be reduced due to switching from turbo Indy
of a Ramp on the Speed of a Trolley For this piece of coursework, I intend to investigate the relationship between the heights of a ramp to the change in speed. I will be measuring the speed from these heights: - * 5cm * 10cm * 15cm * 20cm * 25cm. Formula AIM The aim of this investigation is to find out what the relationship his between the height or a ramp and the change in speed. Hypothesis The greater the height of the ramp the more the speed of the trolley
Speed Limits Jim was leaving work late, and he knew that his wife was at home waiting on him. She had prepared a nice meal for their anniversary and was sitting on the couch all alone. As Jim pulled out of the plant and onto newly paved two-lane highway, he noticed a large white sign with the words “speed limit” and the number “50.” It was a thirty minute drive home, and he could easily make up the time he lost at work if he could just drive as fast as he wanted. For the next half hour, however
out the Speed of Light Through Perspex Aim To find out the speed of light through Perspex by passing a narrow ray of light through a D-Block of Perspex, by using the same concepts and ideas as Snell's Law. Background Light is an electromagnetic wave. The speed of light depends on the medium through which it propagates: it goes fastest in a vacuum, almost as fast in air but considerably slower in glass. Because of the special role it plays in many parts of physics, the speed of light
Speed Skating has been around for a while now. This specific sport has many different techniquies, and skills. There is a lot more to skating then putting on shoes that have wheels and going on a wood floor skating around in circles. In 1863 James Plempton had the idea to actually invent part of the skate. After James had spent time inventing it, James had thought it would be necessary to add something more to the skate. James added what he liked to call the “Fire Rocket”, which able’s the skate
Should Highway Speed Limits Be Increased? Should highway speed limits be increased? Should we strike down every sign that the government posts and uses to regulate the speed limit on the thousands of highways around the country? Should we trust the driving ability of each and every person to drive within a reasonably safe speed? The response that most people lean toward is one of negativity. People automatically assume that the speeds presently posted on our highways are there only for our own protection
How Concentration Affects The Speed Of A Chemical Reaction Aim --- To investigate the effect of concentration of acid, in the reaction between dilute hydrochloric acid and magnesium ribbon. Preliminary Research -------------------- The rate of a chemical reaction is the measure of how fast the reaction takes place. In a reaction particles must collide and overcome the fixed amount of energy for the reaction to take place. This energy is called the activation energy. The rate
The literature review on road bumps encompasses a wide array of enquiries on the development of speed bump systems that can respond instantaneously to traffic conditions. Speed bumps are raised sections of roadway designed to limit the speed of motor vehicles. They are four meters long, between 76 to 100 millimeters high, and can cover all or a portion of the width of a roadway. A speed bump works by transferring an upward force to a vehicle, and its occupants, as it traverses the bump. The force
light is too understand its speed—a speed so great that nothing with mass can ever reach it. So what is the speed of light? It is 299, 792, 458 meters per second or 186,000 miles per second, but humans didn’t always know that light was this speed—at one point in time humans thought that light could travel any distance in no time at all. Later experiments were made to measure the exact speed, but lets start from the beginning. One of the earliest questionings of the speed of light was done by a Greek
