Mass Density Lab
Experiment #1: Mass, Volume and Density
Performed: 2/2/11
Turned in: 2/9/11
The purpose of this experiment is to verify the independence of X and Y motion for a projection. We watch the professor perform this experiment. The equipment used in this experiment was a projectile launcher (ME-6800), a drop shoot accessory (ME-9859), one photogate (ME-9204A), white paper, carbon paper, two time-of-flight timing pad (ME-6810), two balls (ball 1 and ball 2), and an interface computer. Ball 1 is dropped from rest (free fall), and ball 2 is simultaneously projected horizontally (projectile motion); successive positions of these two balls are separated by equal time intervals. At any given time, both balls have the same y-position, y-velocity, and y-acceleration (g= 9.8 m/s2), despite having different x-positions and x-velocities.
Procedure/Raw data:
This experiment was completed using the already mounted projectile launcher (ME-6800). In this experiment, the program measures the flight times of two balls. The solid ball was placed in the free fall position and the hollow ball in the barrel of the projectile launcher. This was later reversed to test all possible flight times. The professor placed two time-of-flight pads at the two places where the balls would land. The launcher cord was pulled so the balls would be released. The …show more content…
The data table tells us differently. The balls hit the ground at the different times for all experiments. When the hollow ball is free falling and the solid ball is in the projectile the flight time differs .02 to .01 of a second. When it is vice versa the flight times differ .03 to .01. At no time are the flight times the same. The hollow ball hit the ground 1st in each experiment no matter which position it was
