Discuss the unit of distance. What questions do you have about it? What additional info would you need in order to explain this unit in the report. Discuss the unit of distance of the soda bottle that was used in this experiment. The unit of distance could be measured using the metric system, which would be centimeters, or meters or it might have been measured in inches or feet. My question is which unit of measurement did my lab partners use to measure the soda bottle. What conclusions would you draw about the speed of the glider as it moved along the air track? What factors might account for these data? What could you guess about how your lab partners arranged the track? I would say that the soda bottle seemed to gain speed as it went along the track since it starts at 1.7 bottles/beat, goes to 2.1 bottles/beat to 2.8 bottles/beat to finally the whole trip was 3.2 bottles/beat. Therefore, it obviously increased in speed somehow. Anything might affect the data for instance if the volume and mass decreased as it went around the track then it’s speed would increase, if its mass was increased suddenly while in route of the track then the speed would decrease. I would take a guess and say they arranged the track at angle going down for the whole length of the track …show more content…
How would this affect the data? How would this new information change your conclusions regarding the speed of the glider as it moved along the air track? Well, it would not change the actually data of the test run, but it does mean that Gabby was not actually watching and observing the experiment. Therefore, I would question the data that they received on whether it was accurate or perhaps even made up. I would want to know who recorded the data and if it was someone else, then the data is fine. However, if it were up to me I would just redo the experiment, just to be on the safe
We put a rectangular piece of cardboard vertically in the middle of an empty rectangular box. One side of the box was filled up with damp soil, and the other side was filled with dry soil. We filled the soil up to the level of the rectangular piece of cardboard, so that the cardboard wall would not deter the sowbug from crossing. We gathered 4 sowbugs, and placed them in a petri dish. We placed the sowbugs one by one on the border between both soils. Each of us tracked one sowbug, and diagrammed the movement. Every minute we would make a mark of where the sowbug had travelled. We continued this process for five minutes. We took the sowbugs out of the chamber, and placed them back in the petri dish. We repeated the experiment under the same conditions. Because we were short on time, we kept the same sowbugs for the second experiment
* In case you are curious, the engine rpm got up to about 7000 rpm and the track speed got up to about 60 mph or more during this clip. I supported the track with a stand and ran the throttle while an observer ran the camera.
[8.3] In what ways do you think your results would have been different if you had sampled at a different height on the rock?
In this experiment, there were several objectives. First, this lab was designed to determine the difference, if any, between the densities of Coke and Diet Coke. It was designed to evaluate the accuracy and precision of several lab equipment measurements. This lab was also designed to be an introduction to the LabQuest Data and the Logger Pro data analysis database. Random, systematic, and gross errors are errors made during experiments that can have significant effects to the results. Random errors do not really have a specific cause, but still causes a few of the measurements to either be a little high or a little low. Systematic errors occur when there are limitations or mistakes on lab equipment or lab procedures. These kinds of errors cause measurements to be either be always high or always low. The last kind of error is gross errors. Gross errors occur when machines or equipment fail completely. However, gross errors usually occur due to a personal mistake. For this experiment, the number of significant figures is very important and depends on the equipment being used. When using the volumetric pipette and burette, the measurements are rounded to the hundredth place while in a graduated cylinder, it is rounded to the tenth place.
Possible sources of error in this experiment include the inaccuracy of measurements, as correct measurements are vital for the experiment.

...der was designed to hold a pilot on his stomach in the center and would control the movement of the craft through a process that would become known as "wing warping". (Cite) On a windy day, the brothers tested their glider. Wilbur was the pilot while Orville and a man named Bill Tate held ropes that would steady the glider like a kite. The craft was successful and lifted fifteen feet off the ground. (Cite) After the successful flight though, the brothers ran into a slight set back. While adjusting the glider, a wind lifted the craft off the ground and the glider was smashed onto the ground a few yards away. This crash was not the last setback the wright brothers experienced. After many successful flights later on, the brothers began to look for a way for the glider to be self-powered, and not have to rely on the wind. Their glider needed a propeller and an engine.
Many people are amazed with the flight of an object, especially one the size of an airplane, but they do not realize how much physics plays a role in this amazing incident. There are many different ways in which physics aids the flight of an aircraft. In the following few paragraphs some of the many ways will be described so that you, the reader, will realize physics at work in the world of flight.
The Terminal Velocity of a Paper Helicopter Introduction. Terminal velocity is the resulting occurance when acceleration and resistance forces are equal. As an example, a freefalling parachutist before the parachute opens reaches terminal velocity at about 120mph, but when the parachute is opened, terminal velocity is reached at 15mph, which is a safe speed to hit the ground at. This experiment will be no different, as I will be examining the terminal velocity of a freefalling paper helicopter.

With our question, we need to know how long it takes for sugar to affect someone’s heart rate. The first experiment that I looked at said that it takes 1 minute to make their heart rate change. On the same website, there was one that said three minutes. In the end we decided to comprise it the middle at two. After looking at other similar experiments we came to the conclusion that it will take approximately 2
Take the measuring tape and measure the length of the string the bob is hanging on. Ensure that this length stays constant throughout the experiment.
Ever since I was little I was amazed at the ability for a machine to fly. I have always wanted to explore ideas of flight and be able to actually fly. I think I may have found my childhood fantasy in the world of aeronautical engineering. The object of my paper is to give me more insight on my future career as an aeronautical engineer. This paper was also to give me ideas of the physics of flight and be to apply those physics of flight to compete in a high school competition.
