Julius Robert Oppenheimer is remembered as a well-renowned citizen-scientist whose efforts in the field of theoretical and experimental physics produced a cornerstone in weapon development and the knowledge of the atom, but what can we say accounted for Oppenheimer’s success in his endeavors? Was it his drive for the knowledge of science, or was it the patriotism he had for his country that drove him to work endlessly on the creation of the atomic bomb? In an article in Modern American Poetry…

To do this experiment you will need two subjects that have different arm lengths. In this experiment Subject 1 had an arm length of .81 meters and Subject 2 had an arm length of .77 meters. It is crucial that the subjects have different arm lengths because if they don’t your results will be invalid. The first step in this experiment is to set up the camera using the tripod and insert an SD card. Next, position the camera perpendicular to the sagittal plane along the x-axis in regards to the…

Conclusion At first, my hypothesis was that P-waves would move faster than S-waves. I thought this because P-waves went straight and S-waves where lobbed to the side. My hypothesis was correct, since P-waves had a more focused channel of energy unlike S-waves, which bended to the side. This causes S-waves to go slower and P-waves to go faster. When the experiment was done, P-waves averaged at .64 seconds and S-waves averaged at .68 seconds. On the P-wave experiment, I pulled the spring back…

Our Rube Goldberg machine used several physics concepts in order to complete its simple task, which was to turn on a Roomba. One of the most prominent physics concepts within our project was gravity and/or gravitational potential energy, which could be seen in places such as the inclined planes and the hammer swinging down. Gravity was the downward-pulling force that allowed the energy to be transferred from the top level, to the Roomba on the floor. The toppling rule was another major concept…

The Dropper is an extraordinary ride unlike any other. As the coaster winds rapidly through Sherbert Park it presents breathtaking scenery as riders travel over and through Willow River in Hudson, Wisconsin. This mid-north roller coaster, constructed of metal, has four cars per train, holding six people per car. One train will be on the track at a time. The ride was designed to appear like a torpedo, featuring a point on the front car, and black cars with burnt orange outlines, and red flames…

Over the course of the roller coaster height lab My group and I had to answer the question “ does the height of the ramp affect the speed of the marble”. We answered that yes the height of the ramp will make the speed of the marble increase. Our hypothesis was wrong, but, My group and I have discovered that the height of the ramp will not affect the speed of the marble. We also Discovered something new which was that the speed increased and decreased abnormally as we went along in the lab. Over…

The egg drop project we did involved many physics principles. One of them was air resistance, which happened because the egg dropped and it accelerated, while the velocity increased. Then the resistance of the air to the egg box motion also increased, which means the upward force of air resistance balances the downward force of gravity, so the egg box dropped at a constant speed. We attached balloons to the box we made in order for the box to pass through the air while softly landing. We believe…

~~~Science Project~~~ Experiment 1: Materials~ 2 eggs Needle Scale Bowl Marker Question? What is the difference between weight and mass, and can two objects that have the same mass be different weights? Hypothesis The difference between weight and mass is that mass is the measurement of how much matter is in an object and it will remain constant regardless of gravity. Weight is how heavy an object is depending on the gravitational pull on the object. Step 1: Zero out the scale. Step 2:…

Grant Alexander Pd#6 11 November 2016 Trebuchet Engineering A trebuchet is a machine used in medieval siege warfare for hurling large stones or other missiles. How this machine works is not to complex but is also fascinating. The object that is being shot is held in the sling, which is on a launch trough whose job is to make sure the shot is straight. Also the trough is there to prevent the sling getting caught in the framework of the trebuchet. When putting the arm of the trebuchet down,…

Problem: how does the angle of trajectory effect the horizontal distance of a bottle rocket Background research: When an object is in the air and has no forces acting on it other than gravity it becomes a projectile. (Henderson, 1996) Gravity causes the projectile to accelerate toward the ground in a uniform arc like a rainbow does. this shape is known by scientists and mathematicians as a parabola, and objects that fly in the shape of a parabola are said to be in parabolic motion. A projectiles…
