The results of this lab concur with my theory, and demonstrate that one can virtually predict the range of a projectile by using the right procedures. There was the possible chance of air movement due to the air conditioning/heating system and people moving about the room, however this air movement is so picayune that error caused to the lab from this factor would be too minuscule to show up in my data. Note that net displacement over time duration T, along the chosen y axis, is zero i.e. time it takes for the projectile to land back on the inclined plane. So, let’s begin with time of flight, T, i.e. We performed this lab in an indoor environment that had no influence from outside factors. The applications can be varied and complex, utilizing one, two, or three dimensions, describing some form of projectile motion. Now, the acceleration along the x axis is g sin and acceleration along y axis is g cos. Moreover, human error in determining the last decimal place of the measured range values and the measured Δy value, as well as the placement of the range target paper at the predicted range measurement could affect the resulting average range. I do not think wind resistance is a factor in this lab. When aligning the mini launcher at 40.0° and the tape measure from the ground to the mini launcher using a plumb bob, parallax error could affect the resulting measurements due to the angle of observation. (b) The horizontal motion is simple, because a x 0 a x 0 and v x v x is thus constant. There were possible sources of error that were present in this lab. Figure 5.29 (a) We analyze two-dimensional projectile motion by breaking it into two independent one-dimensional motions along the vertical and horizontal axes. Range, Height, Flight Time Theorem The the range x r, height y h, and the ght time t r of a projectile launched from the origin with initial velocity v v 0y j. The predicted range was in close proximity with the average range the 0.018-meter difference between the two ranges resulted in a percent difference of 7.279%. can be derived from the projectile motion equations. By splitting the 0.033-meter difference between the highest range value and the lowest range value, I discovered that the range measurement uncertainty is 0.0165 meters. Throughout this lab, I have predicted the range of a projectile using a derived equation and certain variables, such as Vo, θ, and ΔY, in order to recognize how close my theory came to the average range found. Equations for the Horizontal Motion of a Projectile The above equations work well for motion in one-dimension, but a projectile is usually moving in two dimensions - both horizontally and vertically.
