Is Relative Velocity Crucial for Rocket Launch Direction?

Click For Summary

Homework Help Overview

The discussion revolves around the concept of relative velocity in the context of rocket launches and how it relates to the direction rockets are launched. Participants explore the implications of Earth's rotation on rocket velocity and trajectory.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants discuss the relationship between the direction of rocket launches and Earth's rotation, questioning how relative velocity contributes to achieving higher velocities. There is a focus on clarifying what "relative velocity" refers to in this context.

Discussion Status

The discussion is active, with participants providing insights and seeking clarification on the concept of relative velocity. Some guidance has been offered regarding the importance of specifying the reference point for relative velocity.

Contextual Notes

There is an ongoing exploration of assumptions related to the effects of Earth's rotation on orbital mechanics and the implications for fuel conservation during launches.

Hi TheronSimon! :wink:

Tell us what you think, and then we'll comment! :smile:
 
Since the Earth rotates from west to east, rockets are launched from west to east This is done to aid in increasing the velocity of the rocket because the relative velocity becomes the velocity of the rocket + the velocity of the Earth thus giving the rocket a higher velocity. What this entails is that, the rockets have a higher velocity and so they conserve fuel which in turn helps conserve the environment and having less of an ecological foot print.
 
Yes, that looks good! :smile:

I think you should make this part a little clearer …

… you haven't said what the "relative velocity" is relative to (and why it matters in achieving a particular orbit). :wink:
 
would the relative velocity be relative to the earth? since its going into orbit?
 
(just got up :zzz:)

that's right! :smile:

(and the orbit is not affected by the Earth's rotation :wink:)
