Parachutes - a Science Experiment

11. Using the volume(s) you just calculated for regular vs. heavy duty samples as well as your dimensional measurements (length and width in cm) from Part IV of this experiment, calculate the height, or thickness, of each sample of aluminum using the formula V = l x w x h.  In the formula, V stands for volume, l for length, w for width, and h for height. Once again, you will have to use your algebraic skills to manipulate the formula, to solve for height.  You must show all your work. (15 pts)

The original question was, “What is the effect of air pressure of a soccer ball on its bounce, ramp travel, and catapult travel?” The hypothesis stated that if a soccer ball is inflated to 5 different air pressures (namely 6.9 kPa, 31 kPa, 55.2 kPa, 79.3 kPa, and 103.4 kPa), then the soccer ball that is inflated to 103.4 kPa (15 PSI) will perform the best in all three tests: namely the bounce, ramp, and catapult travel tests. According to Soccer Ball World, higher air pressure correlates to further travel. This is due to that fact that higher pressure improves the rebound of the soccer ball off of a player’s foot, and less energy is lost to deformation on a stiffer ball. However, after experimentation, the ball that was inflated to 55.2 kPa

However the inconsistencies in the data were that we had designed a fair test and therefore we could only test on modification at a time. One inconsistency in the data depended on which person in my group wound the lever and string which propels the mousetrap car to go down the runway this causes an icosistinsy in the data as each one of us will whines the string on the mousetrap a different way therefore causing an inconsistency in the data.

(a) What is the capacity (saturation missing ratio) of the rising air at 3000 feet?

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

Describe the experimental method, state its advantages and disadvantages, and distinguish between independent and dependent variables.

4. What units were needed on the number 1.77 to express the density of jet fuel?

SQRT(2 * F * T / H) = (2 * 80 * 200,000 / 1.00)0.5

If you’re like me, then you enjoy the outdoors and the adrenaline rush that comes with trying new things. Yet, base jumping off the Perrine Bridge or skydiving out of a plane without a parachute remain on your list of, “No… not happening.”

According to Dictionary.com accessed on October 1,2017, skydiving is the sport of jumping from an airplane at moderate or high altitude and free falling using one's body to control direction or movements before opening one's parachute.

* In every experiment there are variables that affect the way an experiment will go. The three types of variables that are measured are Independent, Dependent, and Controllable variables. In my experiment the Independent variable is the three different models of paper airplanes that I have chosen to make and experiment with. The Dependent variable includes the distance the paper airplane goes. The Controlled variable is me making sure that I throw the paper airplanes from the same starting point a well as the same weather conditions. The controlled variable is the one that cannot be changed because it would affect the other two variables. In this case I threw them in my house since I have a very long hallway that leads into the front family room and there is no furniture that would interfere with the results.

Step 9: Because we measured the lengths in centimeters rather than meters, we need to calculate are ‘g’ value into m/s2 so we can compare it to the SI unit for acceleration due to gravity. (Eg. 981.4/100 = 9.81 m/s2)
