Physics The Domino Effect Lab Report Essay Example

Physics The Domino Effect Lab Report Paper Controlled Variable: The number of dominoes used (8 dominoes), the distance between the dominoes (2 CM), the loads used as the initial force applied on the amino (egg), the inclined plane used as a platform that will direct the load to hit the first domino (200), the stopwatch used to time the domino effect, the person using the stopwatch, the person releasing the metal weight from the top of the inclined plane, the ruler used to measure the distance between the dominoes. Equipment 1 Inclined Plane 1 (50 g) Metal Weight 4 x 8 (20 g) Metal weight 8 Dominoes (Nun Stacks) 1 Digital Mass Balance (i 0. 1 g) 1 Masking Tape 1 Protractor 1 Ruler 1 Stopwatch (Â ± 0. 01 s) -34290039687500Diagram Analysis of Variables Independent Variable: The mass of the dominoes will vary ranging from 12. 38 g to 82. 38 g. The increase between each of the variable will be constantly 20 g, to satisfy the range of the mass; the original mass of the domino is 12. 38 g, and an additional mass from a 20 g of load will be attached on top of the domino for every change in variable. Dependent Variable: In accordance to the mass for every variable, the time taken of the domino effect to be completed (1st hit to the 8th fall) will also differ. Therefore, the time taken of the domino effect will depend on the change of mass of the dominoes. A stopwatch will be utilized to record the time of the chain of falling dominoes. Controlled Variable: Identified Variables Possible Impact on Results Specific Method for Control Distance between each center point of domino (2 CM) If the distance between each center point of domino differs for every domino in each trial, the time taken of the falling effect will also differ. Making the distance between each domino the same will create the energy transfer from one domino to another domino to be the same as well.

The distance between the dominoes (2 CM) will be measured with a 15 CM ruler. To ensure the exact placement of the domino, a masking tape will be used to mark the center point. Number of dominoes (8) The difference in the number of dominoes used for each trials will definitely affect the time taken to complete the domino effect. The greater the amount of dominoes used, the longer the time taken to complete the effect. Similarly, using a smaller amount of domino results in faster falling time. Thus using inconsistent number of dominoes will likely cause invalid comparison between data points to occur. 8 dominoes will be used for the entire experiment. Mass of the metal weight (500 g) If the mass of the metal weight is different, this will affect the initial force acting upon the domino, and ultimately this will increase or decrease the rate of the falling domino, or it might not even budge the dominoes at all. The same metal weight will be utilized for he entire experiment. Angle between the base and the inclined ramp (200) The angle of the ramp also impacts the placement of the metal weight that acts as the trigger to push the dominoes. If the angle of the ramp is not kept constant, the potential energy stored in the metal weight will be different, thus when it is set into motion, the force that will hit the domino will not be the same. This will then interfere the consistency of the data. The angle of 200 will be set by using a protractor. Type of inclined plane Even though friction is neglected in his experiment, by using a different type of inclined plane, the acceleration of the metal weight will be slightly modified, thus the initial force exerted by the metal weight on the domino will also be altered. The same wooden plane will be utilized for the entire experiment. Starting point of the metal weight If the starting point of the ball is inconsistent, the force applied on to the dominoes will also be inconsistent, thus altering the overall data. The place where the ball will be released will be marked by a masking tape. Placement of the dominoes In order to ensure that the domino effect will move smoothly without any obstruction, the dominoes must be placed neatly in a straight line. This will avoid interruption for the time taken for the domino effect to be completed. A ruler will be used to ensure that the dominoes are placed in a straight line. Digital Mass Balance Different digital measurement tools have different calibration. Therefore, it is a crucial aspect to use the same digital mass balance for every trial because this will help create a trend in the data that is accurate and precise.

How to Write an Original Composition Essay

How to Write an Original Composition Essay Compositions are mainly written in the junior schools in many states. For the teachers they normally have hard times trying to train their students on how to be creative. The students some of the times get tired and they copy the compositions from the articles that they see written in the English language. Therefore the teacher has to take her time in teaching the students how to write an original composition essay. When the teachers get into the classes, they introduce the topic by explaining to the students what composition is. This way they set a background for the students to know what they are going to be writing about. Once they know that it is just a matter of being creative they will be able to create small events and they will in turn learn how to put them down in the papers. This is how they form the foundation of these students in the creative writings. After this now the teachers insist on the essays. The teachers say that they students should know the purpose of writing the compositions. Even if the composition is all about creative writing, the students should read the instructions carefully and understand them then they will be able to base their creativity on what they will understand. This way they will be able to create the right thing for the right topic that the teachers will give them. After they have read the instructions then they will be able to know whether the composition will be written in essay forms, narratives, plays, short stories or poetry. This is because each of them is written in different ways. After this now the students should be ready to write the introduction of the topic that they are going to cover. They must give the readers a clue of what they are going to talk about in the body of their composition. From this part now the students must develop a body of what they will write. This is normally what the composition is all about. In the body writing, the students should first come up with ten points that they want to talk about in their writing. These points should be supported by some ideas as well as details about them. After this the students should group the points into main groups like three of them. These three main groups will form the three main paragraphs in the body. They should be well organized such that the first one will support the second one and so on. The paragraphs should be detailed. The students should also conclude their work. They should base their conclusion from the body, from what they have explained in their body. Then they should draft the work in a final draft. To get a 100% original essay you can contact our online essay service which offers custom written papers in more than 60 disciplines.
