Homework Help Overview

The discussion revolves around the concept of Simple Harmonic Motion (SHM), specifically focusing on the velocity of a mass on a spring when it is at maximum displacement from its equilibrium position.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the relationship between displacement and velocity in SHM, questioning whether the velocity is zero at maximum displacement. Some participants present differing views on the nature of velocity at this point, with references to changes in direction.

Discussion Status

The discussion is active, with participants sharing their interpretations and clarifying their understanding of the concept. Some guidance has been offered regarding the velocity at maximum displacement, but differing opinions remain present.

Contextual Notes

There seems to be confusion regarding the definitions and implications of velocity at maximum displacement, with references to teacher feedback influencing participants' views.

Dx
I am curious to know that if a mass on a spring undergoes SHM. when the mass is at its MAX displacement from equilibrium, its instantaneous velocity is what?
is it zero!

can someone explain?
Dx :wink:
 
Physics news on Phys.org
Well, just before the mass hits the max displacement, the velocity is +deltaV, and just after it is -deltaV. You have to go through zero to get from + to -.
 
Okay!

Dx scratches his head.
I said at MAX displacement that deltav is + or - Max but my teacher says I am wrong. It must be less than max but not zero as youve kinda explained, i think
Dx :wink:

Right?
 
You had it right the first time: The speed at the extrema of position is zero.

If you are moving this way ----->
and then this way <-----

then at some point you had to stop[/color] and turn around.

Hello,

Thanks!
Dx :wink:
