Discussion Overview

The discussion centers on the relationship between kinematics and dynamics in the context of motion. Participants explore whether kinematics can fully describe all types of motion, particularly in relation to the forces involved and the transition from kinematics to dynamics.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Ron suggests that kinematic simulations could describe all motion in a general sense, especially in one dimension, but questions the boundary between kinematics and dynamics.
  • Another participant asserts that dynamics accounts for the forces that cause changes in motion, implying that kinematics and dynamics serve different purposes rather than competing descriptions.
  • There is a question raised about whether there is any motion caused solely by forces that cannot be described by kinematics, with one participant claiming that all such motion can be kinematically described.
  • Another participant reflects on their studies and expresses appreciation for the insights shared in the discussion.

Areas of Agreement / Disagreement

Participants express differing views on the completeness of kinematics in describing motion, with some asserting that kinematics can always describe motion caused by forces, while others are exploring the nuances of the relationship between kinematics and dynamics. The discussion remains unresolved regarding the extent to which kinematics can fully encompass all types of motion.

Contextual Notes

There are limitations in the discussion regarding the definitions of kinematics and dynamics, as well as the assumptions about the types of motion being considered. The transition between kinematics and dynamics is not clearly defined, leading to potential ambiguity in the claims made.

Hello everyone, My name is Ron and I'm currently a student at ITT Tech, and taking a more than basic physics course. I currently have a 4.0 so I'm doing quite well, so I'm not just looking for answers. I love blogs and discussion forums so we will be seeing a lot of me.
Well the thing today is, Kinematics and whether or not they describe all motion. I do believe that kinematic simulations could possibly describe all motion in a general sense, and very useful in a single dimension. Now where this study confuses me is where does kinematics end and Dynamics begin. I know that dynamics goes into the forces acting on motion and changes that may effect the motion.
But what motion is caused by force only that could not be described by kinematics?
Thanks for everyones time and take care.

That's what kinematics is by definition: A description of motion.

Now where this study confuses me is where does kinematics end and Dynamics begin. I know that dynamics goes into the forces acting on motion and changes that may effect the motion.

You've answered your own quesiton: Dynamics (also called kinetics) takes into account the impetus that gives rise to a change in motion.

But what motion is caused by force only that could not be described by kinematics?

None. You can always kinematically describe motion caused by forces. It's not as if kinematics and dynamics are competing descriptions, they do different things.

Dynamics also can be thought of as the forces generated due to motion.
 
Being that for the last couple days I have been studying the heck out of this stuff, and its an online course, so i have no help other then myself and resources like this. I see what you guys are saying now, and I appreciate your comments. Thanks again
