2. Set the battery voltage to 10V where the positive is on the right of the battery.

8. When finished recording your numbers from the two trail experiments take the average of each trial and compare the final results.

If I am having an issue with wires it may be caused by a break or crack in the wire. First thing I need to do is unplug the power to my computer and bring out any cables that I am planning on testing for easy access. I can disconnect both ends of the wire and put my multimeter to the Ohms setting. Then put my positive and negative ends of my multimeter on the separate ends of the wire to see if the wire has continuity. (Sears PartsDirect, 2015)

During the late 1900’s, fuel efficiency was given very little thought by automakers. Instead, they competed with each other by coming out with larger and more powerful

The mousetrap car traveled 1.75 feet from the starting line during Trial 1. Modifications were made to the mousetrap car due to the short distance travelled. The string was reduced in length to prevent it from tangling with the drive axle and the string was reloaded in each trial. With the shorten string, the mousetrap car travelled a linear distance of 15.50 feet during Trial 2 and 16.25 feet during Trial 3. The vehicle started at the same point in the three trials.

When mass is added to the propeller car the average speed and acceleration(a vehicle's capacity to gain speed within a short time) begins to decrease because of the amount of gravity and friction acting upon the object. All the iterations done were within 500 centimeters of distance and different amounts of weight were added to the car each trial. The mass increased while the speed decreased. When we had 0 grams placed on our vehicle it traveled at an average of 4.56 seconds, when 50 grams were added to the vehicle it slowed down having a average of 5.57 seconds, on the last trial 100 grams were added on the vehicle it took 5.73 seconds to cross the finish line. The way I graphed those data points was by putting the average time to travel 5m(s)

Our objective in this science project was to make a pendulum ride for Northwood High School that could be securely utilized by students. We needed to make a ride, "with a time of precisely 1.5 seconds, which will give a ride that is not too quick, not too slow, but just right" (Northwood Land Article 1). The ride couldn 't be higher than 75 cm, it couldn 't make an angle more prominent than 45 degrees, and distinctive quantities of individuals could be on the ride at once so we should have been ready to have diverse weights that still support with the well being capabilities. Our three hypotheses for this undertaking were that expanding the quantity of individuals will make the ride go slower, expanding the edge will build the period time, and ultimately, an expanded string length will expand the period time. With a specific end goal to test our speculation and achieve the 1.5 period time, we needed to figure out how to test every variable. We chose to consolidate the components of weight, angle, and string length to discover which mix of the three would make a period time of 1.5 seconds while in the meantime, attempt to demonstrate or refute our hypothesis. Altogether, we needed to make three information tables.

This project relates to some of Newton's laws. Using some of these laws, I can make my dragster

ML had developed a policy of selling manual machines and renting automatic machines. Manual machines did not cost much, did not require service, and could be modified to attach different fasteners inexpensively. Automatic machines were rented on an annual basis because they would have been more expensive to sell and it provided annual income to ML. However, about 700 of the rented machines were returned each year. During the time that machines were in inventory, ML would modify the machines to attach different fasteners. This was expensive with an average cost per modification of $2000. If all 700 machines were modified during a given year this would have cost $1.4 million per year. It was also industry practice to provide preventative maintenance and

Lastly, I will be using a piece of string which will be the same piece of string used throughout the experiment.

Once the foot cord and clip have been connected to the power supply, the artist will turn the power on to the power supply, and test that they have a good connection to the machine. You will hear a buzzing sound when the machine is turned on.

For my Independent Study project, I decided to work with Matthew Doherty to design and build a solenoid motor using Inventor and 3D printing technology. The purpose of this project was to expose us to the greater functions of 3D printing as well as a way to study electricity and the mechanical properties of engines. Because of the vast application of solenoids, specifically in automobiles, we decided that building a solenoid engine would provide us with the best model to study both electrical and mechanical design properties and functions. In prior classes, specifically Principals of Engineering and (AP) Physics, we have been exposed to basic models of engines, but we have never been able to actually

Results were gathered three different types of motors; a DC motor, servo motor, and a stepper motor. Table 1 displays the results for the DC motor experiment The “number of weights” column represents the number of 1.6755 ounce-force hexagonal weights hanging from the DC motor. Starting at zero weights, the motor was activated by pressing

Next, the participants removed the resistor from component springs on the AC/DC lab board to record the value of the resistance.
