Nt1310 Unit 6

Potential energy is energy that is stored in an object due to its position. The roller coaster has high amount of potential energy at the beginning of the ride. Throughout the ride, potential and kinetic energy are constantly swapping back and forth until the ride ends. Each time the roller coaster goes up a hill it gains more potential energy. The kinetic energy of an object is the energy that it possesses due to its motion. There's a maximum kinetic energy just as the roller coaster passes through the bottom of the loops. At the end of the roller coaster there is more kinetic

The theme in “The Pit and the Pendulum” is death and hope. This is displayed in the poem when the narrator realizes the razor sharp pendulum that has been over him swaying from side to side is not an image, and is getting ready to kill him at any second. In the “Pit and the Pendulum” on page 276 it states, “It was the painted figure of Time as he is commonly represented, save that, in lieu of a scythe, he held what, at a casual glance, I supposed to be the pictured image of a huge pendulum, such as we see on antique clocks.” This means the whole time the narrator was in the dungeon he thought the pendulum was nothing but an image of time. When the rats bite through his restraints, he has a feeling of hope that he will escape and not die He feels the same thing

1. The ball has potential energy while momentarily at rest at the top of the path.

The soldier also says that the pendulum “swung through the air” (Poe 274). The movement of the pendulum is similar to a clock, which goes along with the theme that the pendulum symbolizes time. Depending on how low the pendulum is, the life of the soldier is slowly getting closer to ending. The pendulum provides imminent death just like hell provides imminent and lasting torture. Watching the pendulum as it descends closer to him tortures the soldier mentally as if he is in hell. When the soldier uses the rats to save himself from the pendulum, it reminds the reader of hell because rodents are imagined to be in hell. The pendulum is symbolic of a clock and life ending, making it a key element in the idea of the story being read as a descent into hell.

Kinetic energy is the energy that happens due to motion. A fast moving ball has more kinetic energy than a slow moving ball. A ball in motion type of motion has no kinetic energy. Potential energy is the energy in an object due to its height above the ground. When a ball is brought above the head it is potential energy but when the person holding the ball lets go of the ball gravity pulls it down and as the ball drops the potential energy is converted to kinetic energy and as it approaches the ground the potential energy decreases and the kinetic energy increases.

This data is reliable as there were multiple trials that were conducted during the span of one class period with no interruptions. The data was also collected in the same way each time and with the controlled variables of strength of gravity and mass of the weight on the string kept to a constant as they were unchanged during the experiment.  However, the poor and difficult to use apparatus and the errors in the data show that this experiment is unreliable and cause the controlled variable of the degree of the swing difficult to keep consistent.

Introduction/Purpose: The purpose of the experiment was to understand equilibrium, which can be broken down into translational, rotational, total, and static equilibrium. Understanding equilibrium and its varying forms lead to the understanding of how force and torque play an important role in not only establishing equilibrium but physics as a whole. Relevant Theory: A body at rest or moving with a constant velocity along a straight line is in equilibrium. Translational equilibrium exists when the sum of the forces acting on the body are zero; while, rotational equilibrium exists when the sums of the torques acting on the body are zero. Total equilibrium is obtained when translational and rotational equilibrium is maintained.

By definition from wikipedia, a pendulum is a weight suspended from a pivot so that it can swing freely. On the more spiritual aspect of a pendulum, it is exactly that, only the weight is normally a semi precious stone such as a clear crystal quartz, amethyst, citrine, smokey quartz or other various stones. A pendulum is usually six to eight inches in length, having the weight on one end and a pivot on the other that allows the item to freely swing.

To gather our information, we set up a pendulum and raised its stature to 70

I can understand that pendulums can have both kinetic energy and gravitational potential energy as their bobs move from one extreme to the other.

means that the time, T, of the period of the simple pendulum equals twice the square root of the length. It was hypothesized that the data collected would support the empirical, within reasonable percent error. By determining the graphical relationships between different variables and their effect on the period of the pendulum, the raw data revealed an equation.

This was later shown to be purely mechanical, though, with the swinging of the heaviest pendulum merely rocking the shelf a little and throwing off the beat of other clocks (1).

Question 3: After testing out the double pendulum, do you think the angle needed to undergo simple harmonic motion would be a big or small? Why do you think it occurs at a big or small angle? (Application)

The purpose of this experiment was to analyze the conservation of mechanical energy of a harmonic oscillating spring-system. In addition, this observation involved analyzing to what affect some of the mechanical energy was lost or dissipated into other forms of energy, despite the experiment 's attempt to minimize the dissipation of the energy as much as possible.
