• Use EXCEL or any other software of your choice to plot the postion as a function of time (position on Y-axis and time on X-axis).
• Do not plot some continuous line but use the scatter plot function, meaning just plot the dots on the plot, no line connecting them.
• Look at the video of my motion and the scatter plot. Identify parts of the graph that represent me moving away from the detector and towards it.
• Find the average velocity in for the parts in which I am moving with a constant velocity (hint: look for linear regions on the plot).
• Relate the sign of your average velocity to the direction of my motion, toward or away from the detector.
• Find the instantaneous velocity form the non-linear part of the graph (i.e. when I wasn't moving with a constar velocity). You can find the slope of a tangent drawn at that moment, so use a very tiny interval to find a slope at that point of interest.

Features ot the Motion Detector I The Motion Detector is capable of measuring objects as close as 0.15 m and as far away as 6 m. The short minimum target distance (new to this version of the Motion Detector) allows objects to get close to the detector, which reduces stray reflections. I The Motion Detector has a pivoting head, which helps you aim the sensor accurately. For example, if you wanted to measure the motion \\Pwul Head of a small toy car on an inclined plane, you can lay the Motion Detector on its back and pivot the Motion Detector head so that it is perpendicular to the plane. \\ u The Motion Detector has a Sensitivity Switch, which is located under the pivoting Motion Detector head. To access it, simply rotate the detector head away fromrthe detector body, - Rubber feet on the Motion Detector provide stability. Rubber feet are located on the back of the Motion Detector, which provides stability when the Motion Detector is placed on its back. Rubber feet on the bottom provide stability when the Motion Detector is standing up. - A standard camera screw mount can be found on the back of the Motion Detector. This screw mount allows you to use the Motion Detector Clamp (sold separately, order code MDCLAMP), which is a universalmounting clamp, or to use it with typical tripod-mounting hardware. Motion Detector Clamp Camera Screw Mount (sold separately) R Connecting the Motion Detector to an Interface _ ' To use the Motion Detector with LabPro, LabQuest 2, LabQucst, LabQuest Mini, Tl-Nspire Lab Cradle, or CBL 2, the Motion Detector is connected to the interface with the included cable. Connect the cable to the DIG/SONIC port on the side of the Motion Detector. Connect the other end of the cable to the interface. To use the Motion Detector with the Universal Lab Interface, connect the cable to PortZ ofthe ULL Using the Sensitivity Switch Slide the Sensitivity Switch to the right to set the switch to the \"Normal\" setting. This setting is best used for experiments such as studying the motion of a person walking back and forth in front of the Motion Detector, a ball being tossed in the air, pendulum motion, and any other motion involving relative] lar e distances or with ob'ects at are poor reectors, e.gy., cogffee lters. J Track Normal 11c other sensitivity setting, which we call \"Track,\" works well when studying motion of carts on tracks like the Vernier Dynamics System, or motions in which you want to eliminate stray reections from objects near to the sensor beam. Using the Motion Detector with Other Sensors The Motion Detector can be used with one or more other sensors connected to the ' interface, Here are some examples of how the Motion Detector can be used for experiments with another sensor: I With a force sensor to study the relationship between force and motion 0 With a force sensor to study collisions and impulse I With a force sensor to study simple harmonic motion 0 With a light sensor'to study the inverse square law c With a magnetic eld sensor to study how magnetic eld varies with position - With a second Motion Detector (LabPro, LabQuest 2, LabQuesi, TI-Nspire Lab Cradle, and LabQuest Mini only) Tips on Getting Good Results with the Motion Detector1 The most frequently reported problems with a Motion Detector are (I) that the Motion Detector does not work beyond a certain distance or (2) that the graph is very noisy. There are a number of ways to troubleshoot these situations, and they are described below. L - 1. See if the Sensitivity Switch makes a dierence. Simply set the Sensitivity Swim to the other position and retry the experiment This change may solve the problem. 2. The Motion Detector does not work beyond a certain distance, erg.,it does detect anything beyond 1.2 In Here are some things to check ifyouhavethrsv problem: , _ , - Check for movable objects (textbooks, ring stands, etc.) in the con ultrasound If possible, move these objects out ofme mans not take a very large object to cause problems. ___,_'._._ l An excellent discussion ofmntion detector \"Physics and Technical Characteristics 0 Madame and Ari Hwnahinon, 71an .

It may not take a very large object to Detector, and then the clamp can be attached to a variety of objects cause problems. If you have trouble with a such as table tops, ring stands, etc. The clamp adds versatility. stationary object causing unwanted echoes, try Vernier Dynamics System (order code VDS) setting the equipment up so that the objects are not The Vernier Dynamics System consists of a versatile track and two in the cone or placing a cloth over the object. This carts with ultra low friction bearings. This system facilitates performing kinematics minimizes the ultrasound reflection. and dynamics experiments. The Motion Detector attaches to the dynamics track in . Also note that the cone of ultrasound extends downward from the center line. such a way that the entire track can be used for motion studies. This can cause problems if you are using the Motion Detector on a hard, horizontal surface. In these cases, try pivoting the head of the Motion Detector to aim it slightly upward. 3. Noisy or erratic data may have a number of causes. Here are some tips. . Sometimes other sound sources can cause problems. If there is another source of ultrasonic waves in the same frequency range, this will cause erroneous readings. Examples include motors and fans, air track blowers, the sound made by the air exiting the holes on an air track, etc. Try to eliminate these sources of noise. If you are using an air track, try changing the air flow volume. . Make sure that the Motion Detector is not placed close to a computer or computer monitor. Warranty . If the room in which the Motion Detector is being used has a lot of hard, sound- Vernier warrants this product to be free from defects in materials and workmanship reflecting surfaces, you can get strange effects caused by the ultrasound for a period of five years from the date of shipment to the customer. This warranty bouncing around the room. Standing waves can be set up between the Motion does not cover damage to the product caused by abuse or improper use Detector and a sound reflector. Try placing a cloth horizontally just in front of and below the Motion Detector. This sometimes helps eliminate ultrasound that is "skipping" into the Motion Detector. . Try changing the data-collection rate. Sometimes Motion Detectors work better at one data rate than another. Rates above 30 Hz do not work well in acoustically live rooms. . If you are studying people moving, have them hold a large, flat object (e.g., a large book or a pizza box) as a reflector. If you have an irregular reflecting surface, sometimes the waves will be reflected back to the transducer, and sometimes not. The results will seem erratic.
