Blue Knob Research Paper

The track begins with a steep climp, building up potential energy in the coaster car. The rest of the

The airtrack was placed on an incline by adding a wooden block to the underneath of one of the airtrack supports. The height (h) of the block and the distance (d) between the supports of the airtrack were measured. Using these measurements, the angle of inclination (θ) was calculated by dividing h/d. Lastly, two photogates were placed on the airtrack and the distance (x) between them was measured. Once the photogates were connected to the Pasco Interface and the Pasco Interface were connected to a computer via USB, Data Studio turned on and the Velocity Gates were setup in Channel 1 and Channel 2, the sliding cart runs were ready to start.. Once the air was turned on, a test run of the sliding cart down the airtrack was completed. When the test run was successful, the start button was pressed and the un-weighted runs began. We had two people watching the data be collected, one person catching the sliding cart at the bottom of the airtrack and one person placing the sliding cart back at the top of the airtrack. When the measurements and data were collected for the first set of 10, the second set of 10 was started. This set consisted of the sliding cart being weighted. When all 10 measurements were collected, stop was pressed on Data Studio to end data recording and the numbers from both sets were transferred to Excel to be

1. Place a plastic measuring trough on top of the digital balance, and press the "tare/on" button so that the mass of the trough will be "ignored." The digital balance should read "0.000 g" after this step.

1. Place the pegboard upright and connect the ramp to the pegboard using the large, metal hook. Make sure the pegboard is connected to the tenth hole from the bottom.

It is best to change the initial velocity until the dot and the car seem to move roughly together

Repeat steps 5 and 6 two more times so there is a total of 3 trials for the same length of string. Record all data in the data table.

3. Set up the ramp so that the highest point of the ramp is 10 cm above the top

The marble roller coaster is an energetic fun experiment a lot of people will like. slow and clanking, the string of cars is pulled up to the crest of the tallest point of the roller coaster it goes after the loop the loop but before it hits it realizes it needs to figure what kind of speed the marble needs to make the loop.

First, The procedures of were take an energy car and roll it down a track with a without a sail and record the data from photogate A to B and the time to took to get there make sure the photogate are 555 cm away from each other. Do the same one energy car wit just wheels and one with one 3 times each.

Some of the modifications that we made to our rollercoaster is a tunnel. When we would test out the ride, it would fall off of the track. So we put a paper tunnel so the ball can stay on the track.

17. Place the plates in an inverted position (agar side on top) in a 37٥C

The roller coaster is designed according to safety regulations that prohibit the speed of the car from

Using Vernier, we clicked collect while releasing the cart after motion detector starts to click. This was done moving the hand quickly out the path. Using logger pro, indicated which portion was to be used by dragging across the graph to indicate the starting and ending times. Then the linear button was clicked to perform the linear regression of the selected data. The Linear Button was used to determine the slope of the velocity vs. time graph, only using the portion of the data for times when the cart was freely rolling. We found the acceleration of the cart from the fitted line. Record the value in the data table. These steps where repeated 5 mores times. Measured the length of the incline, x which is the distance between the two points of the ramp. Measure the height, h, the height of the book(s). The last two measurements was used determine the angle of the incline. Raise the incline by placing a second book under the end. Adjust the book so that distance, x, is the same as the previous reading. Repeated these steps with 3, 4 and 5 books.

· I set up the apparatus as shown in the diagram. I then placed a

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
