SUMMARY

The discussion centers on a graph problem related to velocities and equations, where the user expresses confusion over the rapid drop in velocity depicted in their graph. The user expected all velocities to start at v0 but has instead replaced it with three distinct values: vr, vh, and vs. This indicates a misunderstanding of how initial conditions affect the graph's behavior. The feedback highlights the importance of correctly defining initial conditions in velocity equations.

PREREQUISITES
  • Understanding of basic physics concepts, particularly kinematics.
  • Familiarity with graphing techniques and interpretation.
  • Knowledge of velocity equations and their variables.
  • Experience with mathematical modeling and initial conditions.
NEXT STEPS
  • Review the principles of kinematics and initial velocity conditions.
  • Study the impact of variable substitutions in equations on graph behavior.
  • Learn about graph interpretation techniques for velocity-time graphs.
  • Explore mathematical modeling in physics to better understand dynamic systems.
USEFUL FOR

Students in physics, educators teaching kinematics, and anyone involved in mathematical modeling of motion will benefit from this discussion.

Hi people, i was wondering if anyone might be able to see the problem with my graph:

There must be something wrong, since the velocity drops so fast, and i was thinking that they should all start at v0, but this isn't the case.
(The definitions and equation should be in the picture with the graph)
In this picture you will see how i made the equation (maybe there's something i missed):

I don't see why you would think "they should all start at v0" since you have replaced v0 by vr, vh, and vs, three different values.
