ball possess before collision and after collision. The ball that travels down a ramp with a steeper angle, will have a greater velocity therefore produce more momentum because it has a greater velocity compared to the ball travelling down a ramp not as steep. This will then affect the amount of kinetic energy a ball possess after collision. The ball that is travelling down the ramp with a slightly higher angle, will possess more kinetic energy before collision but after collision it will posses less
Italian luxury liner Andrea Doria and the Swedish American ship Stockholm collided on the night of July 25th, 1956. Prior to their collision, a study in 1948 had been done, on the busyness of the New York harbor, and it recommended that ships traveling east go 20 miles south of the Nantucket lightship. Had these ships heeded this advice a collision might never have occurred. The Andrea Doria, captained by Piero Calamai, was headed towards New York harbor with 1,134 passengers on board. On this same
The ‘Landolt iodine clock reaction’ is a well known experiment characterised by a notable clear-to-blue colour change. This experiment is often used to determine the rate at which reactions take place. This colour change transpires when I2 reacts with 1% starch and NaHSO3 to form a blue starch and iodine solution. The rate of reaction is accurately recorded with a stopwatch as soon as the blue colour change is visible to the human eye. Rates of chemical reactions can be defined as “the amount
2251, an unused Russian satellite. Due to Kepler’s laws of orbital motion and the objects being as close they were to Earth’s gravitational pull, the two satellites collided at about five miles per second (Parker, greeniacs.com). The result of the collision proves Kessler’s concerns, as a cloud of thousands of pieces of broken equipment and satellite parts was created, which is now in Earth’s orbit. The true danger of space debris relies in the speed of each piece. Since each piece travels at around
and in aqueous or equilibrium systems this rate is dependent on the variables such as the reactivity of reagents, initial concentrations, temperature induced fluctuations and any means of catalysis. (Oliver,n.d.)(Jircitano, n.d.)(Blackburn,n.d.). In order to measure rate the change in concentration in a particular reaction must be determined as well as the time of which this occurred. However studying the concentration at any time during a reaction is problematic since the reaction must be stopped
Running head: Egg Drop Lab Report Egg Drop Lab Report Jon Johnson Rochester Area High School Egg Drop Lab Report Introduction The objective of this project was to create a structure that will protect a raw egg and prevent it from breaking when being dropped from a minimum height of two meters. A decent hypothesis or prediction one could develop before any experimental trials would be as follows. The structure that provides the longest duration of impact between the falling egg the
successive steps. The general make up of back-arc basin is defined with emphasis arc extension caused by surface kinetics, properties of the down thrusting slab and the effect of lateral mantle flow on this slab. These steps consequently illustrate how back-arc basins were formed during the subduction of the Tethys Ocean lithosphere and building of island arcs. The Kohistan and Ladakh island arc systems are focused on in the western Himalaya both boarded by the Main Karakoram Thrust (MKT) and the
An Introduction to Chemiluminescence Chemiluminescence is the is the production of light without heat from a chemical reaction. In this reaction, energy is released as electromagnetic radiation in the visible light spectrum. It does not require the absorption of electromagnetic energy to excite molecules into a higher energy state. Instead, the energetics of the reaction itself releases energy as light. This means that there there is an intermediate molecule in an excited state which returns to
the most passes or gained the most yards. Football provides some great examples of the basic concepts of physics! Physics is present in the flight of the ball, the motion of the players, and the force of the tackles. This web page will show you how physics applies to these areas of football. What Exactly Is Physics and What Does It Have to Do with Football? When you throw a football across the yard to your friend, you are using physics. You make adjustments
Destruction: Critical Review Loftus and Palmer’s study on the interaction between language and memory was based on the hypothesis that the phrasing/leading questions used to question an eyewitness can alter the event memory. The study specifically looks at how people recall the speed, vehicles were travelling at when involved in road traffic accidents. The paper spoke in brief about other evidence to support their Hypothesis, this was relevant and valuable when assessing the results of the study. There were
