Does The Speed Or Velocity Of The Car Change Due To The Magnetic Field Present?

1156 Words5 Pages

Research Question:
Does the speed or velocity of the car change due to the magnetic field present?

Background information:
We know that s=1/2(u+v)t where, v= velocity/speed (m/s), d= displacement (m), t= time (s). u=initial velocity (m/s)
When an object moves, it often undergoes changes in speed and motion. The equation used above is an equation of motion, In that specific equation, acceleration is constant acceleration due to gravity. The area of the graph on this equation shows us the rate of change of displacement.

Aim:
To prove that the time taken for the car to reach the end point is more with the magnet present compared to the car without the magnet.

Hypothesis:
My hypothesis is that the time taken for the car with the magnet will …show more content…

The systematic errors are the ones that come up due the errors made by me while taking the measurements which are represented on the graphs. Also, there might be a delay in the time taken as my reaction time and the time taken by the car could differ since the time taken is shorter than my reaction time and the error is bigger in comparison. Along with that, the deviations caused by the magnet and the aluminium strip causes a major difference in the actual time taken compared to the time calculated.

However, the experiment was quite successful despite the errors that occurred. The results obtained are mostly consistent and support the hypothesis stated at the start of the experiment. The time taken for the car with the magnet will take more time to travel the distance on the aluminium strip compared to the car on the plastic strip as the magnet will cause friction and deviations on the path.

More amount of trials and precision and a better range of distances could have been more accurate and constant which would lead to a better result. I could have also used better instruments to make it more efficient and realistic. Along with that, maybe a change of variables could help come to more of an accurate decision and prove the hypothesis

Hastings Point Lab Report

1610 Words | 7 Pages

Introduction For two days, on the 14th and 15th of April, a field excursion to Hastings Point, New South Wales was conducted. At Hastings Point, topography, abiotic factors and organism distribution were measured and recorded, with the aim of drawing links between the abiotic factors of two ecosystems (rocky shore and sand dunes), the organisms which live in them, and the adaptations they have developed to cope with these conditions. Within these two ecosystems, multiple zones were identified and recorded, and this report also aims to identify the factors and organisms associated with each zone. Lastly, using data and observations from the past, predictions for the future of the rock pool ecosystem were made.

Lab Report Chemistry Lab

728 Words | 3 Pages

The lab started off by measuring critical materials for the lab: the mass of an an empty 100 mL beaker, mass of beaker and copper chloride together(52.30 g), and the mass of three iron nails(2.73 g). The goal of this experiment is to determine the number of moles of copper and iron that would be produced in the reaction of iron and copper(II) chloride, the ratio of moles of iron to moles of copper, and the percent yield of copper produced. 2.00 grams of copper(II) chloride was added in the beaker to mix with 15 mL of distilled water. Then, three dry nails are placed in the copper(II) chloride solution for approximately 25 minutes. The three nails have to be scraped clean by sandpaper to make the surface of the nail shiny; if the nails are not clean, then some unknown substances might accidentally mix into the reaction and cause variations of the result.

The actual resulting collision fell only 3.5 cm away from the estimated point and within the uncertainty range. This left a 1.5% error which means the data that was collected was good data and an accurate prediction can be made from it. Considering the uncertainty, a 1.5 % error is good because there is uncertainty in the timing, estimation with the graphing, and also uncertainty with two people dropping the cars for the collision -- they may not have the same reaction

Tootsie Roll Pop Theory

I’m going to talk about other researcher experiment on “How long would it take to get to the center of the Tootsie Roll Pop”. Also my point of view on what I think about their say on their experiment about “How long would it take to get to the center of the Tootsie Roll Pop”. On the Tootsie Roll web page they had three scientific studies that have attempted to determined on how many licks it take to get to the center of the Tootsie Roll Pop. The first one is from a Purdue University where a “A group of engineering students from Purdue University reported that its licking machine, modeled after a human tongue, took an average of 364 licks to get to the center of a Tootsie Pop. Twenty of the group's volunteers assumed the licking challenge-unassisted by machinery-and averaged 252 licks each to the center”.

Nt1310 Unit 3 Lab Report Error

Our lab results on all three data table experiments had a percent error less than 5 percent. When examining these results I can be almost certain it was not systematic error due to the fact that a major percent error was not detected on every trial that was run in each of the three tables. With there being some percent error there is the possibility for random error which are from unknown factors, which could come from impact of outside forces like the air track interfering with the acceleration of the cart. Beings that this was the first lab for my lab partners and I were working there was room for slight personal errors with our use of the computer program as well as the lab equipment.

Therefore, I focused my research on ways to maximize the potential energy. According to Donald (2018), a larger wheel diameter resulted in a further distance. Donald (2018) also explains that the axle turns once each time the string is unwound; therefore, larger wheels rotate more times than the smaller. I also learned that friction and traction were important variables in this experiment. Too much friction could cause the vehicle to stop sooner; however, not enough traction would result in the car “spinning out” (Inspired Learning).

Explain Why The United States Should Increase Speed Limits

1056 Words | 5 Pages

According to National Motorist Association if speed limits were raised and all lanes were moving the same speed, traffic would move so much smoother because it is assumed that everyone has an ideal speed at which they feel comfortable on the freeway and all those people on the freeways driving at that ideal comfortable speed will improve traffic flow. This will not only get you to your destination faster, but it will keep everyone of you safe. The National Motorist Association conducted an experiment in New York and results showed a reduction in automobile accidents. So I think that if Germany and the study in New York proved the reduction in accidents, then I will definitely work throughout the rest of the

With an increase in the aging population there has also been a drastic increase in the demand of diagnostic imaging to aid diagnosis. In the authors experience, there appears to be a patient preference towards MRI as it does not use ionising radiation to obtain its images, therefore, in the public eye it is much safer than CT and X-ray. At this moment in time there are no known biological effects to those who come in contact with the static magnetic field.

The advancement of automobiles over time has directly affected the advancement of society as a whole. Society relies intensely and increasing on private motorized transport, vehicles are expected to become safer, more luxurious and powerful. These expectation, however do not take into account of the ensuring consequences such as greater emissions of air pollutants and greater exposure of people to hazardous pollution that causes serious health problems. All the evidence points to the magnitude of these adverse effects on health and to the need to identify solutions that both reduce risks to health and meet the requirement for mobility. This creates a major challenge to the governments, public health organizations, environment authorities and most importantly to the design engineers.
