Average velocity from a position-time graph?

Click For Summary

Homework Help Overview

The discussion revolves around calculating the average velocity from a position-time graph, focusing on the interpretation of slopes and their relation to velocity concepts.

Discussion Character

  • Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to understand how to determine average velocity given varying slopes on the graph and questions the relationship to instantaneous velocity.

Discussion Status

Some participants provide definitions and interpretations of average velocity, with one suggesting that it is based on net displacement over time. There is an acknowledgment of different slopes in the graph, but no consensus on how to reconcile these with the average velocity calculation.

Contextual Notes

The original poster expresses frustration with the subject, indicating a possible emotional barrier to understanding the concepts being discussed.

what is the object's average velocity during the entire interval?
..i know velocity would be the slope..but there's different slopes so what do i do?
does it have to do with instantaneous velocity?!

physics makes me sad. :(

Well there is no need to be. Average velocity is simply net displacement divided by time elapsed.
 
So..2m/s [N]? :D
 
For the complete path shown, yes.
