Linear Motion Experiment Conclusion

Decent Essays
Linear motion is motion that travels along a straight line. There are several components to linear motion with the first one being displacement. Displacement is the net distance traveled over a specific time interval. That leads into the next two components, which are velocity and time. To calculate velocity you divide total displacement by total time and that give you the average velocity that the object is traveling over the time period. With knowing the velocity you can then figure out the final component which is acceleration. To find this value one must divide final velocity minus initial velocity by time. Linear motion can be broken up into components to get a better understand of the theory behind it.

To do so we had to make sure it was properly plugged into the computer and placed it on the edge of a table making sure it was pointed away from all other tables and chairs. Next we used a meter stick to mark positions that were 1m and 2m away from the motion detector. To test this out one person in the group would stand in front of the detector to make sure that it was picking up that we were the correct distance away. In the last test we had to walk away slowly from the detector to obtain a constant velocity on a consistent basis. Once all of these tests were finished we could start to collect the data for our …show more content…
In loggerpro we used the function that allowed us to fit the graph with a line of best fit to obtain average velocity and standard deviation. The average velocity was .759m/s and the standard deviation was .406m/s. The next portion of the experiment has us do the same thing as in the previous part but walk faster this time. The purpose here is to compare graphs of high and low velocity. So my partner started at .5m and walked quickly away from the detector at a constant speed while I recorded the data. Next we decided to use linear fit to calculate the average velocity and uncertainty. The average velocity was .855m/s and the uncertainty was .344m/s. In the following part of the experiment the purpose was to compare graphs of negative and positive velocity. To do this, my partner stood 2m away from the detector and walked towards it at a constant velocity while I collected the data on the computer. Once again we chose linear fit to calculated the average velocity and uncertainty. The average velocity was -1.011m/s and the uncertainty was

    The first part of the experiment was determining the resolution of the DAC in volts. Before a voltage was applied the noise was determined by measuring the DC offset, the reading of the DMM at an input of zero volts. This offset was removed from the recorded values in order to provide a more accurate reading of the resolution. These corrected values and their corresponding applied voltages can be found in Table 1 of the appendix. The lowest value recorded from the DMM was -9.968V and the highest value recorded was +9.968V making the range of the DMM about 19.94±0.01V. Using the equation for calculating resolution, the resolution was calculated for values of N from 10 to 18 in increments of 2 (recorded in Table 2).…

Before this experiment, I had to research some things about energy. Energy is a property matter, and all matter has it. In other words its ability is to do works. Also, there are many other forms of energy like, sound, heat, friction, electrical, nuclear, and mechanical energy, ext.…

    My Slapshot In Hockey

    Last Thursday, I had a hockey practice, and before anyone else came on the ice, my brother Michael and I were just shooting around. To see how fast my slapshot is, I had him stand at the other end of the ice, and using his phone, see how long it took for my shot to go from one goal line to the other, exactly 60.96 meters. Keeping the puck on the ice the whole time during my shot, changing just the position of the puck, my slapshot took 4 seconds to cross the far goal line, making my slapshot move at a velocity of 15.24 meters per second. This calculation was done by divided the total displacement by the total time, 60.98 meters divided by 4 seconds. Finding the velocity of the puck relates to what we are doing in class, as we are talking about…

    Softball Vs Baseball Essay

    Softball versus Baseball in Terms of Speed and Distance There has been, and will for a long time be, much controversy about whether or not baseball players are better, and the sport is more difficult, than softball. If you were to go to a baseball game and then go to a softball game, it would appear that the baseballs are hit harder and farther than the softballs were hit. The two specific fields even differ largely in dimensions: The baseball field being larger than the softball field. There are many things that may contribute to this, such as softball is generally played by females while baseball is generally played by males, the gender difference also means a difference in muscle and strength.…

    As before the colour excess for M39 is 0.01 resulting Av = 3× 0.01 = 0.03. The apparent magnitude mv is 8.8 and the absolute magnitude Mv is +0.70. The uncertainty in the main sequence recorded the maximum value 15.00 and minimum value 9.00 in Y-axis which gives 15.00-9.00 = ± 6.00. Now we need to plug all known values in equation 1 to calculate distance in parsec as below: d = 10 (8.8-0.70+5-0.03) /5…

    I found the idea for this experiment on Science Buddies and many people have done the same experiment. Each has made different cars that they think will be the fastest or go the longest distance. Others have tested this experiment, but they put a weight such as pennies, marbles, etc. What I am planning to do is make a very lightweight car that can travel a longer distance. The energy that the balloon will force out is called kinetic energy.…

    My marble (at 0 meters) was experiencing no motion. Then, as soon as a force was acting upon it to move the marble, it started to move very fast past 0.5 meters. Then, from 0.5 meters to 1.0 meter, the marble was moving almost as fast as it was in the beginning, but losing a little bit of its overall speed. Then, from 1.0 to 1.5 meters, the marble was slowing down a little bit, so it wasn't as fast as before. Then, from 1.5 meters to 2.0 meters, the marble was experiencing an obvious change in speed, and was slowing down much faster than before.…

    The purpose of this project is to be able use the speedometer readings to approximate the distance traveled with a midpoint Riemann sum. This method is used to approximate the value of a definite integral using subintervals. To complete this project, I first had to ask my parent to take me for a twenty minutes drive on the street. As a passenger, I first had to record the initial odometer reading and then for every two minutes, I ask the driver for the exact speedometer reading and record my data on the sheet.…
