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…

ESTIMATE (METT-TC) Mission: At H-hour, as supporting effort 1, attack in zone to destroy enemy forces vic RCT Obj 2 and seize crossing sites over Stony Creek in order to facilitate the main effort’s attack on MEB Obj 1. As the stationary force, conduct FPOL/BHO with 3/6 at PL Green. Upon FPOL/BHO with 3/6, follow and support 3/6 in order to facilitate the momentum of the main effort’s attack. The overall objective is to destroy the 34th MID in order to deny the 3rd OSC the ability to…

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 in our project, as it was integral for the dominoes and the inclined planes. When work is put into the machine…

ride enter this freefall they travel through a tube that goes through a tunnel under the surface of the Willow River. River life can be seen through the clear walls of the container as they are underwater. While underwater they experience the highest air pressure under the surface than on the surface of the earth. After exiting the awesome underwater tube a little further down the river they fly up Johnson Hill, then circumnavigate around Fire Mountain with its waterfalls flowing down the…

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…

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 that by attaching the balloons it would have less air resistance…

~~~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:…

to push it down as close to vertical as it can go so that the weight can fall the farthest distance, and so that the sling can get pulled with greatest possible horizontal starting force. As soon as the sling is past the trough it is lifted up and away. Then it is swung out in a partial arc because of centrifugal force, or the sling’s inertia. When the object is being released it is because of the releasing mechanism. The releasing mechanism is a loop of the sling’s rope placed around a…

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…
