The closest calculation obtained was 9.6 m/s². None of the calculations for this experiment came out to that exact result. The calculation for each run and measurement is located in the appendices.ĭiscussion: (I have not gotten to this yet accepted value of acceleration due to gravity is 9.81m/s². The tables and graphs for the five runs of the 10cm measurement are attached at the end of the lab report. The possibilities of error are located in the discussion. 427 m/s², which shows some kind of error in the experiment. The actual acceleration for the measurement of 2.5º should be. 3968 m/s² by sin 2.5º an answer of 9.1m/s² is found. For example, the average acceleration of the five runs tested for an angle of 2.5° was. To find g the formula g=a/sin2 or a=g (sin2) can be used. Theta is equal to the angle between g and the y-axis. In the diagram g is equal to acceleration due to gravity, and a is equal to the acceleration of the car down the inclined plane. Diagram 1 shows how the results were obtained. The results of the experiment were not the ones expected. The equations and findings are located in the appendices. Lastly the acceleration due to gravity was found. We first found the average acceleration of the five runs for each of the settings and then found the angle of the inclined plane at each. Once the data was collected, the measurements and calculations were done. Five runs were also done in each of the other settings. The graph of the data was then saved and four more runs were completed at 10 cm in the same way before the bottom of the inclined plane was set at 8 cm, then 6 cm, then 4 cm, and finally 2 cm. Once the car got to the bottom of the track the software was stopped. The car was placed on the track at a distance of 40 cm from the motion detector located at the top of the inclined plane, and released at the same time that the DataStudio began recording. The bottom of the inclined plane was first set at 10 cm from the top of the table. The procedure to this experiment with the list of materials like the one above, can be found in DataStudio Essentials Acceleration Due to Gravity, by Pasco Scientific.Īll equipment was first hooked together and set up so that the experiment could be done. Power Links- used to plug all components together Meter Stick- used to measure how far to prop up the trackįriction Pad- used to keep the track from sliding Motion Sensor – used to measure the acceleration of the Pasco carĭataStudio Software – used to show the graphs and do some of the measuringĭynamics Carts Track from Pasco- used for the car to go down Is Earth the center of the solar system, and is it stationary? The answer of course was that Earth is not the center of the universe, the sun is, and that it is not stationary, but constantly rotating and gyrating around the sun.Ī list of materials used in the experiment is as follows: Galileo found the results of the experiments to lead to the answer of an important question of his time. This experiment will continue to be studied, as its results are as important as any. This experiment tried to attain that same result using the equation g=a/sin2. Theory states that acceleration due to gravity is 9.81 m/s². Galileo did this same experiment around four hundred years ago, only with none of the technology of today’s time and a ball instead of a blue car. The purpose and objective of this lab is to obtain g, acceleration due to gravity, by using an inclined plane, and other materials, and to calculate g using the results. could someone help with writing the Abstract? or if something doesn't sound right? Also. I want to know if there's anything I should have that I don't. I was assigned to do a Lab report on an experiment we did in class.
