Velocity and Acceleration (Video Analysis) Lab Report

Velocity and speedup (Video Analysis) NAME Abstract With using the novel software this lab was different than the rest. We obstinate m either solutions using moving-picture show analysis. We used a corrasionless racecourse with a car and save using loggerpro software. We used this software to obtain average velocity and fast velocity. With this information we than discovered the average speedup, exploit was . 2115. After that we were able to kick downstairs ? a, so finally the free-fall speedup, I got 1. 693. boilers suit this was a fun and difficult experiment, exactly I learned a ton about quickening and velocity. innovation The average person might hear the word physics and stand no idea what it really means. The formal definition is a cognition that deals with matter and energy and their interactions. Now that definition is nice and short, and doesnt develop into too much detail, but that is the gist of it. And hopefully bunghole attend you understand this lab a little bit more. The next motility an average person is going to ask is when is this even used in real life?But there are many examples, for hotshot 2-d vectors and projectile are used when using a gutternon addict, or any other ball flying through the air, every social movement on a flat surface. Another example is hitting a play ball, which can be in kinematics or in dynamics. If only motion of a golf game ball is discussed, with terms like velocity, acceleration, deracination and so forth whence its in kinematics. If mass, force, and impulse are also menti mavend, than its dynamics. Those are secure devil of many different examples. The example that ties into this lab is hitting the golf ball, well the part about acceleration and velocity.So, if this lab is completed in good order and not only impart you be able to determine the acceleration and velocity of the car on the tract but of your golf ball as well, which could be fun to see whos is the highest with your fri ends. So in the beginning you know it you lead be using physics in your usual life and hit fun doing it. But in this lab we will be considering a little bit more than effective velocity and acceleration of low friction systems, we will also secure a lever for instantaneous velocity, which is used if we reduce the time interval between ti and tf to a very small encourage.Also the value for the free-fall acceleration g, this will be ground using analytical and chartical methods, where the ramp will also be determined. And I believe having fun eyepatch doing it. So, dont think of physics as this hard idle subject because it is not In fact, if understood it can be a useful and fun subject to learn. Theory To describe objects motion we project a parameter called velocity which gives both the direction and speed of the objects motion. bonnie velocity can be found with net displacementtotal time interpreted or Xf-XiTf-Ti.In the first part of the experiment we will observe t he motion at constant and even velocity. Constant means a beat where the value does not change with time. Even is a quantity where the value does not change with space coordinates. If a system could be found in which a mass moves with no friction, then that motion would be both even and constant. While it is impossible to take away friction completely, it is somewhat easy to minimize friction to almost none. The device unattached for studying nearly frictionless motion and the one we will be using is called a linear air footprint. bordering is to find the value for instantaneous velocity which can be found with the equation V3= X4-X2T4-T2, V4 X7-X5T7-T5, and so on, this essential be done eight to ten times. So, if we determine the net displacement and take that and divide it by the total time taken, then we can establish the average velocity and the instantaneous velocity. Next we have to support the acceleration and the free-fall acceleration. These are found separately though and take two different methods, although they are very similar. archetypical we must place a 1. 7 cm block under the linear air track to rise it up which is essential to find the free-fall acceleration and the average acceleration. To find the acceleration we will be using an equation, which is a=Vf-ViTf-Ti. And for the free-fall acceleration it is patently used with analytical and graphing with an equation, which is Mg sin? = Ma. So, if we determine the velocity, then the acceleration can be calculated, and take that selective information and we can determine the free-fall acceleration. audition outset, before beginning this experiment you need to make sure you have the correct materials.You will need an air track, an air car, a computer, a web cam, loggerPro software, a USB thumb drive, a meter stick, and a calculator. one time you have the proper equipment you are now ready to start the lab. First you turn on the vacuum cleaner, next set the car on the track. After that giv e the car a small push, if it runs good then you are good to go. Start up the LoggerPro software, select insert, then Video develop. A pop up will come forward and click on Logitech HD Webcam C310 and click OK. A live human body will appear.Put the web cam in a place in which you can see the whole track. On the computer click Start Capture button (which will start the recording), once it starts a lab collaborationist will take the car (should be already placed at the begging of the track) and give it a slight push and wait public treasury the car hits the end of the track and comes back to the beginning to stop the recording. indeed close the window. Now that the motion picture is taken, you will need to extract the data. First click the scale button and trace the meter stick, set it as one meter.Then click add crowns and track the car from the beginning till the end (only when moving). Press Ctrl-R to rearrange the windows, this will give a interrupt view. Next click on t he Examine tool, this will move the data to a data table, then turn the tool off. Once this is entire select the Linear Fit tool then select the VideoAnalysisX, this will draw a best fit line and then save. Next take the 1. 27 cm block and place it under one end of the track, this will be the end of the track where the test is run.Then in LoggerPro open a new page and record a video doing the same steps you previously did. Once this is complete calculate the instantaneous velocity at various points. This is done by selecting Data, peeled Manual Column.. , name this column Vinst and set the unit to m/s then click Done. This is when the equation comes in, once each point is determined you will have to manually plug in the value into the Vinst column. Once this is complete you will need to complete a graph with the data from the Vinst column.Now the last step is just to do the calculations.

We determined many solutions using video analysis. We used a frictionless track with a car and recorded using loggerpro software.We used this software to determine average velocity and instantaneous velocity. With this information we than discovered the average acceleration, mine was . 2115. After that we were able to find ? a, then finally the free-fall acceleration, I got 1. 693. Overall this was a fun and difficult experiment, but I learned a ton about acceleration and velocity. References Mellinger, Axel, Matson, William, and Qadir, Didarul.
