Homework Help Overview

The discussion revolves around the graphical representation of motion for an object projected vertically upward, specifically focusing on y vs. t (position vs. time) and v vs. t (velocity vs. time) plots. The original poster is interested in understanding the shapes of these graphs given an initial velocity of 34.3 m/s.

Discussion Character

  • Exploratory, Conceptual clarification

Approaches and Questions Raised

  • The original poster asks about the expected shapes of the y vs. t and v vs. t plots, suggesting a parabolic shape for the position graph and a diagonal line for the velocity graph. They seek clarification on these assumptions.

Discussion Status

Some participants affirm the original poster's questions, indicating a level of agreement on the expected shapes of the graphs. However, further exploration of the reasoning behind these shapes is suggested, particularly in understanding the underlying physics.

Contextual Notes

The discussion includes questions about the nature of the graphs without delving into specific equations or detailed explanations, maintaining a focus on conceptual understanding.

Can anyone please explain to me what a y vs. t and a v vs. t plot would look like for an object projected vertically upward with an initial velocity of 34.3 m/s?

Would the y vs. t plot look like a parabola?
Would the v vs. t plot look like a diagonal line starting at 34.3 m/s and ending at -34.3 m/s?

Yes and Yes on both questions.
 


Thanks PhanthomJay

Do you understand why?
