Mousetrap Car Research

On a larger scale, the example of a Lego made motors efficiency can relate to that of a modern day car and the efficiency / energy waste that comes from it. The internal combustion engine is an engine in which the combustion of a fossil fuel mixes with air in a chamber of the operational fluid flow circuit.

To create a mousetrap car and measure its performance. We will also see where force and energy is impacting on the performance, for example friction will impact on the cars performance as it generates heat and slows to car down thus meaning that the car may not travel as far as it should. Another force that is demonstrated in testing of the car kinetic energy, without kinetic energy the car would not travel at all.

ABC Mouse is a global educational initiative that offers a full online curriculum for pre-school thru Kindergarten. The goal is to help children build a strong foundation for future academic success. ABC Mouse is a subscription based program (see their website for pricing information). ABC Mouse offers over 350 lessons, at six different levels, and more than 2,000 individual learning activities. The ABC Mouse program has received a number of awards and citations, including a Parents’ Choice GOLD Award in 2011. Go to: www.abcmouse.com to learn more about this popular new

In this lab, we applied the concepts of velocity,force, acceleration, time, and distance in order to calculate which trial had a higher velocity. We also learned the relationship between each of the factors and how altering one plays a role in the other factors. For example, if we were to apply more force the velocity of the cart would increase, as well as the amount of time it took for the cart to go down the

After the experiment had been conducted, the investigator concluded that the original hypothesis did not fit the outcome of the testing of the Beetle Robot. While it was hypothesized that the device would move and react in the same

Next, there is a while loop that continues to run if the left encoder is less than the value of the number of revolutions multiplied by the counted ticks per revolution. After this, if the computed motor ticks are unequal between the two motors, the function is written to where the vehicle can adjust and correct itself if it starts to drift to one side. This is done by if-else statements in which each motor power is adjusted. Variables used in the driveStraight() function were used in the turnLeft () function as well. The function contains a turningTime variable, which is set to the inputted angle multiplied by 1000 and is divided by the inputted turning speed. Like the previous function, if-else statements were used to adjust each of the motors power to make a proper turning angle. At the end of the function, the command encoder.clearEnc(Both) clears both the encoders counted motor

The two types of friction of the mousetrap car are rolling friction and static friction are the two types of friction that may affect the performance of the mousetrap car. The problem of the friction did I encounter and how do you solve them one types of friction i encounter was the static friction I had to take off some glue from the stick that had my wheels and to open eye screws. The factor did take into account to decide the number of wheels you decide to chose for the mousetrap car I saw a video of a car that had 4 wheels and it ran really fast, so I thought a 4 wheeled car would run fast or at least the four meters. What kind of wheels did I use in each axles I use tires as my wheels on each axles. I think the affects on using big wheels

The pill bugs lab was done to solve the problem of which type of food the pill bugs preferred, cucumber of pepperoni. My hypothesis was that the pill bugs will favor cucumber over pepperoni. In order to carry out this experiment, we used the chamber method to determine which food was favored by the pill bugs. Pieces of cucumber and pepperoni were placed on each end. Then five pill bugs were placed in each chamber, and their movement was observed and recorded. Because the results were so close to each other, we concluded that their reaction to the stimulus was a kinesis reaction, and it is only random. My hypothesis was not true because the standard error from the number of pill bugs in cucumber chamber and pepperoni chamber overlapped. This means that there is no scientific reason for why the pill bugs chose cucumber over pepperoni. I learned many new things in this experiment, such as, how to use a choice chamber, and how to calculate the standard deviation and error of the data. Also, I learned how pill bugs react to an outside threat.

It is also important to reduce the friction between the car body and the track surface in order to have high kinetic energy which results in having a high velocity. All of these points were taken into consideration while thinking about the design. Then three designs were made using SolidWorks program, one of them was with a hole in it to have an aerodynamic car which is known to be the fastest car. And the wheels of the car were made separately with a specific dimension. To determine which design must be the final design for the project the drag coefficient was calculated using Solidworks, and based on the results the design with the hole in it, had the least number of

The balloon powered race car will be powered by the balloon. The balloon will be blown into and the straw will be the source of the air going into the balloon and then pinched so there is no release of air, then release the air, measure the distance and speed of the car when air is released. This uses the three Newton laws and they are when an object is at rest it stays at rest and an object is in motion it stays in motion in a straight line at constant speed unless acted upon by an unbalanced force, the next is the acceleration of an object depends on the mass of the object and the force applied, the last is every action there is an equal and opposite reaction.

The background research had talked about different types and sizes of wheel and the distance in can cover in a certain amount of time.

Kinetic energy is the energy of motion. The formula for kinetic energy is half of the mass times the volume squared. When the kinetic energy increases, the potential energy decreases. Notice, that is the opposite of what happens to potential energy. Since kinetic energy is the energy of motion, while the mousetrap car is in motion, it has kinetic

The toy has uses two main energies, Kinetic and Potential. Potential energy is made by the pulling back of the car. Kinetic is made when after the car is

Trap-Ease America located in Costa Mesa, California was created by a group of investors looking to market a new and unique mousetrap worldwide. The mousetrap was invented by a retired rancher, who had built and patented his work. Trap-Ease America obtained the rights to market this product worldwide, in return providing the inventor with a royalty fee of 19 cents per unit sold. Trap-Ease partnered with a plastic manufacturer to build these mousetraps with specific dimensions. The company also hired Martha House, as the president of Trap-Ease America. The trap was designed similar to a teeter-totter, in which one side would remain elevated while the opposite side would sit on the ground.

Information that they need is to see if there are any Companies ( competitors ) that produce similar products (mousetrap) do not have the similar technology with Trap-Ease product, that they have a better mousetrap, efficient and easy to use and without any risk to any injured or poisoned by how the mouse trap compare to a traditional ways. So this is a new breakthrough in technology mousetrap, this is the major information to be evaluated by them so that they feel this
