Data Analysis Does the mass of a pinewood derby car affect the speed? If the mass of a pinewood derby car affects speed then the more mass the car has, the faster it will go. The procedures for the experiment were; Go get a pinewood derby track, car, scotch tape, quarters, and a timer. Set up the track. Make the derby car with the instructions included with the kit. Find the mass of the car with no weights added. Race the car 3 times down the track with no weight added. Record times. Add 6 quarters to the car, find the mass then race it 3 times. Record the results. Add 6 more quarters, find the mass then race the car 3 times, and record results. Find the mean for each weight division. Find out which one was the fastest. The control group is the car with no weights added. The experimental groups are the cars with weights added. An independent variable is the weight. The dependant variable is the speed. Some control variables are the track, wheels, and body style. Three different pinewood derby masses were tested in the experiment. 140g, 173g, and 204g. Each weight division was tested 3 times. There was only one car used. This car was altered to show differences in …show more content…
The hypothesis was that the more mass a car has, the faster it will go. This hypothesis was partially rejected though. One reason that the car got slower on the last race could be because of wear and tear. It took awhile for the track to work properly. The end has a wall,and if the car hit it at the high speeds it was going, it may damage the car. Another reason the the results may have not been correct could be because of where the car started. The car was just placed at the top, but never in the same spot. At the very end the car was placed in the very back, which may have made the time longer. Before, it would not be in the very back. This issue may have added .50 seconds or more to the time. Some extraneous variables could be placement, and wear and
Science 1. Free ears in dogs are controlled by dominant allele (F), and attached ears are controlled by the recessive allele (f). In addition, Short dogs is due to a dominant allele(S), and long hair is due to a recessive allele (s). Which of the following is the genotype of the dogs with free ears and short hair? a. ffss b. FfSs c. ffSs d. Ffss 2.
Our names are Sue-Sue Murray and Harriet Townsend from Mr. Enns' Orange Science class. In Phillip's gym, there is a problem having to do with the safety of whomever athletically involved there. For example, if somebody were to be running across the court and tried to come to a complete stop before running out of bounds it would be extremely hard for them to do so without running into the wall. The experiment we conducted was to measure the average distance it took to come to a complete stop while running full speed for fifteen meters. The average distance it ended up taking for the eighth grade class of 2020 was 195.1 cm.
The independent variable was the type of battery used for the motor. The dependent variable was the time the motor spinned. The control variables where the materials used other than the battery. The control group was the D-battery and the experimental group was C, AA, and AAA-Batteries.
In wondering how his Welsh Corgi determined the fastest path to reach his ball, Tim Pennings of Indiana University used calculus. He assumed that the dog’s approach to this problem was to “minimize the time by minimizing the distance travelled” (Pennings 1), and as an equation, he used T(y)=z-yr+x2+y 2 s , where T(y) as the time it takes for his dog to reach the ball taking the path A to D to B, which Pennings assumes is the path his dog will take (1). The total distance from A to C is expressed as z, and r is the running time while s is the swimming time. This equation is in conjunction with Figure 1. Figure 1: Paths to the Ball, Do Dogs Know Calculus?, Pennings, Page 178.
The Change of Two Brother’s Relationship Certain circumstances can change a person for the better or for the worse. In “The Red Convertible” by Louise Erdrich, she demonstrates how the Vietnam War completely altered a young man’s personality. Two brothers, Henry and Lyman, who has an inseparable bond in the beginning of the story were portrayed also as best friends.
This paragraph tells you everything that you need to know about the Bugatti Veyron. Some of the facts that you should know about the Bugatti, which was launched in 2010 are it can reach up to 1200 hp. It can also go from 0-100 km in 2.5 seconds which set a new record for the fastest car in the world. ("Bugatti Veyron Super sport. ")The car can get up to 431 km as its top speed, and this is what makes it pretty much unbeaten.
Kinetic energy is produced when the car hits the tree.
HYPOTHESIS I hypothesized that a mousetrap car without a lever arm would generate more power, and a larger wheel diameter would result in a further distance. I believe that my mousetrap car will generate enough energy to travel fifteen feet. My mousetrap car is designed to quickly release energy and travel farther than most. However, the quicker release of energy can cause the car to steer towards the right. RESEARCH

In the Penny Boat Lab, we made a boat to hold pennies in water. First, we collected materials we needed which were scissors, a ruler, water, pennies, aluminum foil, a triple beam balance and a container. Using the ruler, we measured the foil 15cm by 15cm, then cut excess pieces. Next, we had to fold the foil into a “boat”. After, we measured the mass of our boat using the triple beam balance.
VARIABLES: There are independent variables, dependent variables, and controls. the one that is being tested and the one that is the inconsistent variable in the Independent variable like the volume and surface area of the agar cubes. The variable that is kept consistent is the dependent variable such as the percentage of diffusion of pigment in the agar cubes. The constant variable is the features of the experiment that is kept the same throughout the entire experiment such as, the amount of time the agar cubes are left in the beaker and the amount of acid in the beaker.
Skrrt, Skrrt, cars everywhere, people are racing and flexing their whip. As I get out of my cousin’s FRS, I see many groups pull up on the side. I think to myself “Oh my, aye, that’s insane”, from stance cars to sleepers you get a variety of everything. Looking out to spot my one of my favorite cars, a Lancer Evolution enters from nowhere and makes me turn my head from one side to the other.
When it comes to sports cars there are a variety of brands that come to mind such as Infiniti, Chevrolet, Nissan, BMW, Mercedes-Benz, and Porsche. However, there are two cars that are always competing, The Nissan GT-R, and Porsche 911 Turbo. Both cars are excellent machines, but they are quite different in every way. The Nissan is Japanese, while the Porsche is German.
In 1989, McLaren Cars (later McLaren Automotive) was established to create high-performing road-cars based on Formula One technology. The first car was a sports model that delivered lightning acceleration (0 to 60 mph in three seconds); it was called McLaren F1. Interestingly, it was a three-seater coupé with the driver's seat in the middle. The original F1 was presented in 1992 and many variations followed, including GT and GTR racing models. Recent
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).
