- body-fixed frame of reference vs lab frame of reference
Hello Everyone,
I am trying to understand the usefulness of a body-fixed (body-centered) frame of reference versus a lab frame of reference . The body-fixed frame is attached to the moving body and changes orientation exactly as the body changes orientation. From the perspective of an observer sitting at and using to the body frame to describe the body's motion, the body does not move at all and nothing changes... On the other hand, the ground, lab-based reference frame is obviously useful since the body moves a relative to it and we can determine its position, velocity, etc.
Why would we use a body-frame at all? The rigid body under consideration is composed of many points. I guess we can describe the overall motion of the body by looking at how the body-fixed frame attached to it changes relative to the frame . Is that the reason why we use ?
Thanks
