Fist name, last name Physics ### Lab: Rotational Equilibrium The purpose of this lab was to analyze the physical effects of torques on an object and all the factors that can influence the magnitude of its strength and force. In lecture, we learned that although the magnitude of the force can have a strong effect on the rotational velocity of an object, the location or displacement of that force can have an enormous impact on the force’s effectiveness to do work. In this experiment, we saw, first hand, how a small force can have as much of a dramatic impact on an object as a larger force if the displacement is right. The goal of this experiment was to balance a meter stick at its center of gravity using different weights on opposite ends of the stick. Making the left side our positive direction, and our right, the negative direction was essential in proving algebraically, the results of the experiment.
Measure and record the total volume. Part 2 - Combining Two Liquids A lab technician measured 20 mL of rubbing alcohol into each of two graduated cylinders. She then combined the two liquids. The combined liquid filled a graduated cylinder to a level of 39 mL. Observations: Predicted Volume (mL) Actual Volume (mL) 50 mL of marbles + 50 mL of sand 100 mL 75 mL 50 mL of marbles and 50 mL of sand + 50 mL of water 150 mL 100 mL Analysis: If you added the marbles to the sand instead of vice versa, the marbles would sit on top of the sand rather than sinking in, which would make the volume larger.
As a result of doing so, this allowed the chip to work faster in calculating more intense, complex numbers (Janeba, 1995). Errors were later found in the FPU instructions for division; incorrectly dividing certain floating numbers. Discovered but not reported by Intel during the early production of the chip caused negative publicity for the company. In the summer/fall of 1994, Dr. Thomas Nicely was computing the sum of the reciprocals of a large collection of prime numbers and noticed a difference between two sets of numbers (Janeba, 1995). By double checking his work, he found that the results differed significantly from theoretical values.
Human error was also a factor in this experiment as we had to wind the machine ourselves in order to produce the oscillation. We then found amplitudes and velocities using the data given by the computer. The spring oscillations decreased over time in this
3. This is a shorter variation of the 100 throws - with possibly more focus on indoor ultimate: • 10 roll curve backhands • 10 straight backhands • 10 IO or skip curve backhands • 10 roll curve • 10 straight forehands • 10 IO or skip curve forehands • 10 hammers 
Again over 5m-10m, this time each drop or throw away is counted by the pair then multiplied by the years they've been playing ultimate for some form of punishment!

9. Find the average time for each clay with different mass to hit the ground. 10.Find the speed of the parachute in each trial and the random uncertainty from the repeat trials. 11.Plot a graph of mass (x-‐axis) against time (y-‐axis) to look for a relationship. If the first graph is not linear it will be necessary to further process the data and plot further graphs to try to find a
Once the investigation is complete they can begin to reconstruct the accident. During the reconstruction phase, physics is used to determine several aspects such as speed of the vehicles, their approximate positions at different times during the accident, and stopping distance (Glennon, 2001). If the cause of the accident is readily apparent then a reconstruction of the scene may not be necessary, such as with many of the multi-car pile-ups. Many of these accidents occur because of environmental factors such as fog, smoke, ice, or dust storms. Even though the main cause of the accident is environmental and out of the driver’s control, there are certainly things that could be done to minimize the effects.
The tank could have been placed over the differential, where it would have been somewhat safe in the event of a rear-end collision. However, considerations of trunk space and manufacturing cost dictated that the tank be placed farther back, between the differential, which had several exposed bolt heads, and the rear bumper. In this position, a rear-end collision might push the gas tank forward into the differential, where the exposed bolts could rupture the tank, possibly leading to a fire or explosion. Ford engineers knew that the Pinto’s gas tank design was susceptible to explosions from rear-end collisions, mainly from previous experience with the Capri, a European car produced by Ford on which this problem had occurred and had been fixed. In rear-end collision tests, a Capri with a rear-mounted tank was susceptible to gas tank rupture in impacts as
This may have entered the detector during the experiment, skewing the data. This is an experiment that needs to be performed in total darkness, but it was not possible due to the blinds not blocking out all of the sunlight and the computers being on throughout the experiment. A final cause of error may have been the yellow and green filters2. They have been inadequate, insufficiently blocking high frequency light. These unwelcome high energy photons would have ejected high energy electrons, allowing them to surpass the cathode-anode potential, which would have increased the measured stopping
Unfortunately they are not consistent between each other, and that is one of the major endeavors of physics, to find a theory that unifies them both. With E=mc^2 where E is energy, m is mass and c is the speed of light. Because of the equivalence of energy and mass, the energy which an object has due to its motion will add to its mass. In other words, it will make it harder to increase its speed.
