Lab 3 Report Section 03: Constant Acceleration: Dry Ice Puck on a Ramp Pivot Interactivities Giselle Paz 6/12/21 PHYS 1403
INTRODUCTION In this lab, we learn how to construct a velocity vs time graph. To do this, we watched an interactive video that displays a dry ice puck sliding on an aluminum ramp. In addition, we learn how to analyze a position vs time graph with a non-constant velocity, linearize data, generate a mathematical relationship between position and time, and make predictions regarding the puck’s motion. MATERIALS In this lab experiment, we used the following materials: Dry Ice Pucks Aluminum Ramp Stopwatch Protractor Ruler PROCEDURE 1. Allow video to play and watch phenomena (dry ice puck sliding down the aluminum ramp). 2. (Set the video to Mass A and ramp angle #9) Use the tool icon, select the stopwatch and reset. * Note: if we want a position vs time graph for the sliding puck on the ramp, we cut to frame 42 (ribbon no longer is attached to puck) . After, find the angle of the ramp using the protractor tool, and measure. *Angle measure: 22 degrees 3. Use the ruler tool and measure how far the puck travels to the bottom of the ramp. *Measurement:164 cm
4. Now you can choose a mass and ramp angle; I chose Mass D: 25 g and Ramp Angle #9. With the mass and angle, we will be recording our data into a table to later create a graph. Continue this process until the puck has reached the bottom of the ramp at time intervals of 0.1s. DATA & DATA ANALYSIS Table and Graph 1: The table below shows our recorded data of all the positions and times until the puck had reached the bottom of the ramp. We recorded the time from 0.1s to 0.9s in cm .
