Pendulum Lab

In Edgar Allan Poe’s story, “The Pit and the Pendulum,” Poe, uses the horror elements of ____Isolation_________, ______Madness______, and__Disorentiation_____ to add suspense to the story. In the beginning of the reading of The Pit and the Pendulum, the setting is at the Spanish Inquisition and Edgar Poe sees figures that look like angels, or judges. One of the important horror elements is Madness. The author Edgar Poe states “In other conditions of mind I might have had courage to end my misery at once by a plunge into one of these abysses; but now I was the veriest of cowards” (Poe 5). The quote is an example of the horror element because he wants to end his misery at once, he has been through so much that he just wants to end his life but

The Pit and the Pendulum is about a man who is sentenced to THE PIT during the Spanish Inquisition. The story starts out as describing his trial and quick sentence to THE PIT. Next as he is in

The purpose of this lab was to test the relationship between velocity, position and time. As well as identify how accelerations affects an object's velocity and time. In this experiment, we will collect data on velocity, speed, and time. We used the equation Y=mx+b, in order to compare the velocity of each trial by comparing the slope and the y-intercept. If the slope was steeper on the graph, this meant that the cart had an increase in velocity. If the cart maintains at a constant speed, then the cart will have an increase in acceleration. In class we learned about the principles of acceleration, time, and velocity. Acceleration is an object’s increase in velocity. Velocity is how

After collecting data and analyzing the results the group concluded that tension will always be greater than mass for uniform constant motion due to the presence of θ. As the length of the string for the flying toy increased, θ decreased in both trials for the cow and bat. For instance, when the bat had a length of 0.86m, the calculated θ was 34.4°, but when the length was shortened to 0.61m, the θ increased to 36.5°. The period was also shortened when the length decreased; therefore, velocity decreased as string length increased while acceleration increased with a

Using Gravitational Force as a Measurement Tool Answer the following questions about the results of this activity. Record your answers in the boxes. Send your completed lab report to your instructor. Dont forget to save your lab report to your computer Activity 1 Record your data from Activity 1 in the boxes below. Enter the data for the sample you used in each trial (5000 rpm, 10000 rpm, etc) in the appropriate columns and the corresponding g-force, number of layers, and position of layers position results. You will need to use the following formula to assist with your laboratory report G-force 0 00001118 x radius of centrifuge arm x (rpm)2 The radius of the centrifuge arm for this instrument is 10 cm. Speed 5000 rpm 10000 rpm 15000 rpm

In this case G is 6.673×〖10〗^(-11) m^3 kg^(-1) s^(-2). So all units must be in meters (m), kilograms (kg), and seconds (s). Now the radius between Object X and its moon is 19,570 km must be changed to meters, through a conversion factor of 1km = 1000 m. Also, it takes the moon 6.4 days to orbit Object X, so we must change days to seconds. To change days to seconds we must change days to hours to minutes to seconds.Now that the measurements are in the correct units, we can start substituting them into Kepler’s Third Law. First we plug in the radius (1.957×〖10〗^7 m) into the numerator. Since the radius is cubed, 1.957×〖10〗^7 m will become 7.50×〖10〗^21 m^3. Next multiply m^3by 4π^2 to get 2.96×〖10〗^23 m^3 in the numerator.Next we substitute in the gravitational constant (G) and time (P). Since time is squared, 5.53×〖10〗^5 s becomes 3.06×〖10〗^11 s^2 in the denominator. Next we multiply together G (6.673×〖10〗^(-11) m^3 kg^(-1) s^(-2)) and P, which becomes 20.42 m^3/kg. The reason that seconds is not in the units is because G had s^(-2) and P was s^2, so the units canceled each

The clock would lose time because as the value of g decreases, the period increases.

The ratio between the time and where the pendulum is confuses people the most. People found the sine factor to be confusing so Foucault made the gyroscope in 1852 to try and help them understand the concept of time with the pendulum. The gyroscope’s spinning rotor tracks the stars directly. Its axis of rotation turns once per day whatever the latitude, unaffected by the sine factor.

Many great thinkers contributed to the recent discovery of gravitational waves. Aristotle was the first to consider gravity thinking that objects fell to the earth because it was the natural place of the object to be on the ground. Galileo decided that Aristotle’s idea needed to be tested scientifically and he discovered that objects fall with “a constant acceleration along a parabolic curve.” During the Apollo 15 mission, Galileo’s theory that all objects fall with the same speed was proved when officer David Scott held the famous feather and hammer experiment on the moon. Sir Isaac Newton famously contributed his Law of Gravity which mathematically explained gravity. Although it was mathematically explained, the physical nature of gravity

A pendulum is a bob suspended by a string from a fixed point and behaves in an oscillating manner. When released from an angle away from its equilibrium, it swings side-to-side in a periodic motion. The time it takes to complete one full swing is considered the period and the purpose of this investigation is to discover the effect of the string length on the period of the pendulum. This will be accomplished by recording and analyzing data with the use of data tables and graphs.

The objective of this practical is to determine acceleration due to gravity ‘g’ using the simple pendulum model. This is shown when a period of oscillation is seen to be independent of the mass of the mass ‘m’.

With his theory tested with pendelums, almost 100 years later, his theory was used for the invention of the pendulum clock by Christiaan Huygens.

I have placed the results from our experiment in form of a table and will use the average results to form a graph. I have also prepared a graph to show the results throughout the exercise.

* Dependent Variable: The deflection/flexion of the cantilever in metres. This will be measured indirectly by measuring the initial height of the bottom of the cantilever with no mass added (which is equal to the height of the table) and the new height of the bottom of the cantilever after each trial, which will be measured with mass added. Hence, the difference between these heights is equal to the deflection/flexion of the cantilever. The material and other physical properties of the cantilever will be controlled by using the same yardstick as a cantilever for each trial.
