PHY 221 Lab 1 Position, Displacement, Average Velocity Leader: Critic: Scribe: Goals : PHY 211/221 is devoted to the description and explanation of motion . We start the course with the description of motion, a subject also known as kinematics . One good way to describe the motion of some object is to say where it was at what time . We can call this the "position as a function of time", usually written x(t) . Another name for x(t) is the trajectory of the object. In lab, we want to measure the things that we think about in physics. So, we start your lab course with the question of how we can measure where an object is at various times . Materials: Meter sticks Metal angle bracket PC with ULI interface for measuring instruments PASCO Motion Sensor (also known as a "sonic ranger") PASCO cart on aluminum tracks (activity 3-5) Activity: 1. Use of meter stick to measure static positions Pick a spot on your lab bench, just to the right of your PC, to be a reference point for your position measurements. Physicists and mathematicians call such a point the origin of Page 1 of 6 PHY 221 Lab #1: Introduction to Measurements 12/28/2009 http://physics.syr.edu/courses/PHY221.07Spring/manuals/position.html

coordinates . Put down an angle bracket some distance away from the origin. Using a meter stick, measure the position of the angle bracket with respect to the origin (express your measurements in meters). Write it down here: Now, move the angle bracket farther from the origin (along the direction defined by the origin and the initial position), and measure its location again. What is its position now? When you moved the angle bracket from the first position to the second position, you caused a displacement . How big was the displacement? 2.
