Set the Motion Sensor to the "people" setting 3. Connect the Motion Sensor to the Interface. You will need at least 2 m of empty room in front of the sensor 2. Use the Rod Clamp and 45 cm rod to fasten the Motion Sensor to the table, as shown in Figure 1.
In this activity the plots will be done in real-time, that is, as the motion is happening. The position of an object at a particular time can be plotted on a graph. The change in velocity from moment to moment is expressed as acceleration (meters per second per second). The change in position from moment to moment is expressed as velocity (meters per second). As the object moves, the change in its position is measured many times each second.
A sonar ranging device such as the PASCO Motion Sensor uses pulses of ultrasound that reflect from an object to determine the position of the object. Theory: When describing the motion of an object, knowing where it is relative to a reference point, how fast and in what direction it is moving, and how it is accelerating (changing its rate of motion) is essential. This is an excellent way to learn what the graphs mean. The challenge is to move in such a way that a plot of the motion 'matches the graph that is provided. The Motion Sensor is used to detect the motion of a person moving back-and-forth in front of the sensor along a straight line at different speeds.
PASCO Capstone Software Introduction: The purpose of this lab is to introduce you to the use of the 850 Universal Interface and to explore plots of the position of an object versus time and plots of velocity vs. Graph Matching of Position and Velocity versus Time on Equipment: 1. Where the acceleration largest? What is the speed at that point Velocity 2 Consider the Velocity 2 pl What is the difference between places where the slope is large and places where it is near zero Consider the Velocity 2 plot.
