Analysis of Work, Energy and Power Experiment

Procedure: Using distilled water, premeasured containers and objects determine displacement of fluids and density of objects. Use ice and heat measure temperatures in Celsius, Fahrenheit and Kelvin.

1. When we say that something gives us “energy,” what does that mean? What is a biological definition of energy?

To test Newton’s seconds law if whether changing the mass or the force affects the acceleration of an object or a trolley in this case to increase or decrease.

Also, since there is no specific pattern in the change of the acceleration of all marbles, it can be deduced the difference in the accelerations were caused by mistakes in the experiment and not by the change in mass. The outcome of the experiment supports the fact that gravity pulls all objects down at the same rate, since that also means all objects should accelerate down at the same rate. In addition, the results gathered can reflect real life scenes. For example, a skier going down a ramp should know that he can carry as much as he wants and it would not affect how fast he

Overall, there were little to no complications for this experiment. There were modifications made to the first part of this lab, the student written portion. One change was the distances. In the original written procedure, see Attachment 02 of this report, the distances for all parts were noted as; next to the heat source, 5 inches away, and 10 inches away. After testing these measurements in the lab, the distances were alter to be next to, 2 inches away, and 5 inches away. This was done in order to produce more prominent temperature results. The distances for the 10 precision measurements were also modified. Originally the student was to take measurements for 80 seconds, starting at 2 inches away from the heat

Before using Breeze Through It Energy (“Product”) for the first time, read the directions below. The directions are longer than most due to plenty of practical information for easier Product use. Many of the directions are well known and common sense.

In this lab, we have explored the concept of the conservation of energy through the use of an isolated system. Tools such as a glider upon an air track with negligible friction allowed us to mimic an ideal isolated system. Using the values we measured for (velocity, time, and distance) we can see the application of conservation of energy through the transfer of the potential energy of the small mass to the kinetic energy of moving glider. In the graph (ΔPE vs. KE), our value (-1.197 +/- 0.05916) is not entirely consistent to the expected value of -1. Furthermore, in the graph for velocity vs. time plot, our value of 0.5067 m/s2 +/- 0.01709 m/s2 is not consistent with the calculated expected value of 0.646 m/s2. The probable cause of these slight inconsistencies with the our expected values is the unbalanced dropping of the small mass during the experiment. To have a more justified value, we could have done more trials to find the average

This continued until there were 4 weights. The results of the experiment were then recorded into a graph and data table. Data Tables & Graphs Figure 3: Data Table Weight of Cart (g) Acceleration of Cart (m/s2) Trial 1 Trial

A cart of mass (m) is released from rest on a frictionless ramp. Apply your previous knowledge about energy and motion on frictionless tracks to determine what will happen if the initial height (h) of the cart is larger than the diameter of the loop-the-loop. Choose all that apply. (Apply)

However, in the experiment free-fall was not actually depicted because the experiment was conducted in the classroom rather than a vacuum. Any object acted upon the force of gravity is free-fall, but it can not encounter air resistance. The conditions did not reach the criteria, therefore, the data values are less than the actual amount because it is not truly in free-fall. In graph 3 looking at the average grade data, the averages are: -8.065, -9.097, -9.275, -9.506 m/s2from the least to greatest mass respectively. The values are close, but do not reach -9.8m/s2. Random error played a more minor role in the data. For example, in graph two the 10 grams had an imprecise data set. The mass had an indirect effect on the paper as the mass is accelerating. The movement of the trailing part of the spark timer strip through the device could have been indirectly affected based on the rate of the movement of the paper. Therefore, the values of the displacement could have been greater or less. In another way, procedural error could account for the outliers in the data. When the displacement had to be measured for each spark timer strip per mass, the procedure stated to skip 3 spaces of marked dots when recording the data. Where to begin measuring because certain strips were clearer than others caused

* The relevance of this experiment is similar to understanding a real airplane. Paper airplane models are derived from an actual plane these days. The design of an airplane has so much to do with distance, hang time, speed, and many other factors. Understanding the models I have chosen to make help me

Power can be defined in many ways. Most simply, it is the ability to get what you want.

Ask your Team Leader for a full set of guidelines before “Hour of Power” begins

Purpose is signified as “we the people” have the power to change the union. It is the ability to influence the behavior of others. Over the years, we have given to the government, the constitution sets the condition on which that power is able to be used. Power is not handed over, we must reason. We must reason towards a more perfect union.

This experiment consisted of four separate parts. The first part was to adjust the balance to make sure it was working properly, and to measure its
