Car Experiment Lab Report

The bessbug was able to carry 6 weights which has the mass of 18.85 grams, while ten times the mass of a bessbug is 17.6 grams. The maximum amount of weights the bessbug was able to pull was 10 weights which is equal to 31.46 grams. The data shows the strength of the bessbug and how much the bessbug is able to carry in all. The data occurred because the capacity of the bessbug allows the bessbug to carry 10 weights. The data supports the hypothesis because the bessbug was able to lift ten times the weight of the bessbug which is 17.6 grams, and much more because the total amount the bessbug was able to pull was 31.46 grams. The knowledge acquired from this experiment teaches that a bessbug is capable of pulling much more than 10 times the weight of a bessbug. If the group were to repeat this experiment and change that would be made would be with collecting more data, that is more accurate, with a greater range. The changes could be done through multiple timers, experimenting with more weights on the bessbug, to test the capacity even more. Also, experimenting with multiple bessbugs instead of one bessbug, and having the bug go to multiple distances will make the range in data more minded and

There are two main purposes for this experiment. First, isopods were observed so that their behavior could be recorded. Second, we exposed the isopods to a wet cotton ball and dry cotton ball, to determine which stimuli the pill bugs (or Rollie pollies) preferred over the other. In the experiment, five different pill bugs were removed from their usual habitat and placed in a choice chamber 1 pill bug at a time for a total 5 minutes each. It was observed that the pill bugs favored the wet cotton ball over the dry cotton ball. The pill bugs displayed positive behavior towards the wet cotton ball than dry cotton ball or undecided.

The topic that the scientist has researched is the reaction rate of different particle sizes. In the experiment, the scientist will discover how the particle size of Alka Seltzer affects the rate of chemical reaction with water. The independent variable in the experiment is the particle size of the Alka Seltzer, while the dependent variable is the rate of reaction, or the volume of Carbon dioxide. The volume of carbon dioxide will be measured in ml. Also, a few of the constants in the experiment will be the amount of water, and amount of tablets.

In this egg drop project, a container was built to house one egg and was then dropped at various heights. The purpose of this lab was to find how impact time affected the force with which an object, the egg container, hits another surface as the momentum moves to zero. Our hypothesis states that if the impact time is stretched longer then the force exerted on the egg would decrease, making the egg less likely to break. The independent variables for the egg drop project was the height at each drop; the dependent variables were impact time and survival of the egg. The controls were mass, design of the container, and the egg. The container was built to decrease the impact of the force at each drop. The container was able to successfully protect

The goal of this lab was to build a mousetrap powered car. The mousetrap car needed to travel fifteen feet. The purpose of building these mousetrap cars was to demonstrate our knowledge of motion, friction, force, distance, and energy. We have studied these concepts, and each one is a factor in the success of a mousetrap car.

There were many trial and errors but nonetheless, in the end, the marble rolled from start to end with ease. The marble roller coaster demonstrated elements of physics such as energy, force, and the three Newton laws. At the top of the roller coaster the marble possesses a large quantity of potential energy – because potential energy depends on the mass and the height of the object, the roller coaster began at an elevation to increase its potential energy (GPE = m ⋅ g ⋅ h). Newton’s First Law states that an object at rest stays at rest and object in motion stays in motion unless the object is acted upon an external force, also known as the law of inertia. The marble will not roll down (stays at rest) until it is put in motion by being dropped into the track and pulled down by the force of gravity. As the marble slides down the first drop it will lose much of its potential energy corresponding to the loss of height. The marble subsequently gains kinetic energy – kinetic energy is contingent to the mass and the velocity of an object. The marble speeds up as it loses height, consequently, their potential energy is transformed into kinetic energy. Newton’s Second Law states that an object’s net external force is equal to its mass times its acceleration; simply, the acceleration is proportional to the force applied and also the mass of the object. The acceleration of the marble will change through out the roller coaster as it descends through hills, turns and loops. Newton’s Third Law states that with every external force there is an equal but oppositely directed force occurring. Through out the whole roller coaster the marble is exerting force on to the track, but there is a normal force acting against the marble towards the opposite direction of its weight, this way the marble can stay on the track. As the marble continues, it is continuously gaining and losing height. Each gain in height coincides to the loss of

According to Newton’s first law an object will travel in a straight line unless an outside force acts on it. In this experiment, the swinging stopper is swinging at steady speed but since it is being acted upon by an outside centripetal force and therefore it is accelerating. The swinging stopper was set up by placing the string with the stopper through a tube so that the stopper is hanging out the top side of the tube and the bottom side is the clip with the washers. In this experiment, three radii were selected and for each radius three trials were conducted. In each of the trials the swinger would swing the stopper in constant speed in a horizontal plane until 20 revolutions were completed. The time it took for each of the trials was a recorded and then based on that along with the radii measurements the calculations for the centripetal force were conducted. The purpose of this experiment was to measure the period of a swinging stopper for three selected radii in order to calculate the centripetal

To Determine the Time Taken for a muffin paper cup to reach the ground, while Changing the Height of each experiment

A positive acceleration happened in three places of the Rube Goldberg machine. The first was located at the beginning when the first marbles slides down the shoe (inclined plane). Without enough force and acceleration the marble’s hit wouldn’t be enough to make the car move, too much force and acceleration the marble flies out of the shoe. The second instance is when the weight is added into the pulley system, the harder it falls into the cup going down the higher the other cup lands. The third instance is after the chain of dominoes collapse and send the marble rolling down the inclined plane. The speed of the changes the distance it will go, therefore it had to be the exact acceleration in order for it to land into the cup.

In this lab there were five different stations. For the first station we had to determine an unknown mass and the percent difference. To find the unknown mass we set up the equation Fleft*dleft = Fright*dright. We then substituted in the values (26.05 N * 41cm = 34cm * x N) and solved for Fright to get (320.5g). To determine the percent difference we used the formula Abs[((Value 1 - Value 2) / average of 1 & 2) * 100], substituted the values (Abs[((320.5 - 315.8) / ((320.5 + 315.8) / 2)) * 100]) and solved to get (1.58%). For the second station we had to determine the distance required to balance the system and the percent difference. To find the unknown distance we set up the equation Fleft*dleft = Fright*dright. We then plugged in the values (11.35 N * x cm = 48cm *

Confounding factors are factors that impair the accuracy or repeatability of an experiment. In other words, it is an ability to interpret results.

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.

The purpose of this Lab was to identify the density of the unidentified object and determine what substance the unidentified object given by the teacher was. The density calculated in the experiment will stay the same because the density of the unidentified object will stay constant. The Independent Variable of this experiment was the calculated density and the unidentified object given. The Dependant Variable for this experiment was the density. The Controlled Variable for this experiment was mass and volume.

At 21 and with only one year of medical assisting experience. I figure it was an okay job. After all, I was getting paid more than minimum wage. Initially going into a trade school for fast pace and expensive learning that is what I wanted more money in little time requirement. I had learned different things in the medical field. I learn how to verify insurance, call in prescription and had a great deal of customer experience by now. I had the endurance to learn anything. I would be placed in front office and back office. I enjoyed back office more dealing with directly assisting the doctor. Overall, I could handle anything. I was a very flexible medical assistant. I thought I was the best medical assistant they had at Frisco Urgent Care and Clinics as I would get praised for my well-done work. However, I was soon to find out why I was hired and why I was there that day.

The purpose of this lab based on the Drosophila melanogaster (the common fruit fly) reactions. Since the fly has been studied and observed for many years, and known for its unique chemotactic attractions to different stimuli, it was an ideal organism for the study being conducted. In the experiment the purpose was to be able to figure out whether the flies would be more attracted to sugar or bacteria. The bacteria, which is found in flies’ natural food source rotting fruit, was represented by the yeast, and the sugar was represented by the maple syrup. The purpose was to be able to identify which substances the flies were attracted to the most
