Homework Help Overview

The discussion revolves around the concepts of speed and velocity within the context of kinematics. Participants are exploring the differences between these two terms, particularly in relation to motion in straight lines and circular paths.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are asking for examples of objects that move at constant speed in straight lines and in circles. There is a focus on understanding the implications of constant speed versus constant velocity, with some questioning their own understanding of these concepts.

Discussion Status

The discussion is ongoing, with various interpretations being explored. Some participants have provided insights into the relationship between speed and velocity, particularly in terms of acceleration and net forces. However, there is no explicit consensus on the definitions or examples being discussed.

Contextual Notes

Some participants express confusion about the distinction between speed and velocity, indicating a potential gap in understanding that is being addressed through questions and clarifications.

wat moves at constant speed in straight line?
 
Physics news on Phys.org
These are some questions I need to answer..
>What moves at constant speed in straight line?
>What moves at constant speed in circle?
 
anyone here to help??
 
A lot of things can travel at a constant velocity in a straight line.

And I think that when something follows the path of a circle it is said to be constantly changing its speed (accelerating). Although I probably understood this wrong when I heard it.

confusing speed with velocity...
 
Are you looking for examples or what?

Something moving at a constant speed in a straight line has a constant velocity (no acceleration, no net force).

Something moving at a constant speed in a circle, has a constantly changing velocity (centripetal acceleration toward the center of the circle).

hehe I always do.
