The discussion revolves around understanding the comparison between experimental and theoretical values in the context of projectile motion. The original poster seeks clarification on what constitutes a theoretical line and how to effectively compare it with their experimental measurements of horizontal distance and velocity.
The conversation is ongoing, with participants exploring various interpretations of the theoretical line and how to plot it based on the experimental values. Some guidance has been offered regarding the use of equations to derive theoretical values, but there is no explicit consensus on the best approach to take.
Participants note the absence of provided theoretical values, which adds complexity to the comparison process. The original poster has a plot of experimental values but is uncertain about how to determine the theoretical line for analysis.
Touchme said:i measured the horizontal distance and and horizontal velocity.
Touchme said:It is not a plot dependent on time. The plot is x (distance) vs. horizontal velocity. I plugged the values into the equation above and compared the values. But, is there a way I can draw or determine the theoretical line?
Touchme said:how is it represented in a X vs Vx coordinate system?
