Lab 6: Energy The intent of this lab is to show the relationships of energy to a system. For this experiment, we had a spring attached to a car, which was attached to a string that went through a rotary sensor and had a weight attached at the end. By stretching the spring, and causing the weight to drop nearer to the ground and bounce up we were able to determine: the angle of the string and rotations; the car position; height of the weight bouncing up and down; velocity; the stretch of the…

A skid steer loader is a versatile machine, and a must have for anyone in landscaping, large-scale construction, farming, or logging. It has a rigid frame and lift arms you can attach various tools and skid steer loader attachments to. Loaders may be track-equipped or four-wheel drive. The drive system of the loader has no transmission. Instead, it uses pumps and hydraulic motors to power the wheels or tracks. Wheels can drive independently of each other, which makes them very maneuverable.…

Difference between a racing dirt bike and a Trail dirt bikes Did you know that Racing dirt bikes is way different than riding regular dirt bikes? Most people think that they are the same, but they are not very similar. Racing is different from regular riding because of the bikes engin, their suspension, and their tires. Motocross bikes focus on different speeds. Trail bikes are meant for going threw mud and meant for more power. gearing up helps if your trails consist more of long…

In general, the experiment succeeded in demonstrating free-fall by dropping a tennis ball. Distance and time were documented to calculate velocity and acceleration, the quantities involved in linear kinematics. Graph 1 (distance vs. time) suggests a commonsensical relation - longer distance yields longer time. The only exception is at 1.0 m, where its time value (0.42 s) is less than that of a shorter distance (0.5s for 0.5 m distance). Average time was used to construct the graph, and there…

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…
