![]() 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. 4)In a normal projectile motion, what will be the angle of the projectile to get the horizontal range minimum a) 90°. At the half time point (t The total horizontal distance (from the origin to. We performed this lab in an indoor environment that had no influence from outside factors. Projectile Motion The trajectory (the path of the projectile) is a parabola. 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. There were possible sources of error that were present in this lab. 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%. Remember: the only force acting on the projectile, after it has been released, is gravity There are three possible scenarios for projectile motion: Vertical. ![]() The maximum height depends only on the vertical component of the initial velocity. This equation defines the maximum height of a projectile. Call the maximum height y h then, h v 0 y 2 2 g. 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. The expression we found for y while solving part (a) of the previous problem works for any projectile motion problem where air resistance is negligible. 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.
