Comparing Constant Velocity and Accelerated Motion

Click For Summary

Discussion Overview

The discussion revolves around the comparison between constant velocity motion and accelerated motion, focusing on the definitions and implications of velocity and acceleration in each case. Participants seek clarification on the conditions under which these types of motion occur and how they relate to each other.

Discussion Character

  • Conceptual clarification, Debate/contested

Main Points Raised

  • One participant suggests that in constant velocity motion, the velocity remains constant (v = constant) and acceleration is zero (a = 0).
  • Another participant points out a potential contradiction in assuming that an accelerated object can move at constant speed, indicating confusion in the definitions.
  • A third participant states that acceleration signifies a change in Cartesian velocity, implying that non-zero acceleration cannot coexist with constant velocity.
  • Further clarification is sought regarding whether acceleration can be constant while velocity is also constant, with some participants asserting that this is not possible.

Areas of Agreement / Disagreement

Participants express disagreement regarding the relationship between constant velocity and acceleration, with some asserting that constant velocity cannot occur with non-zero acceleration, while others seem to misunderstand the definitions involved.

Contextual Notes

There are unresolved assumptions regarding the definitions of constant velocity and acceleration, and the discussion highlights potential confusion over the conditions that define each type of motion.

I want to know the comparison between a body in motion with constant velocity and accelerated motion?
Like a body when it is motion with constant velocity its velocity is constant(v =constant) and acceleration (a=0)...?
and when a body is in accelerated motion its velocity will be constant(v =constant) and acceleration is also constant (a =constant) or acceleration has some value.
Please elaborate to make me clearer as possible.!

You assume an accelerated object moves at constant speed. This is the contradiction that confuses you
 


Acceleration means a change in Cartesian velocity.

Since acceleration is the rate of change of velocity, you cannot have constant velocity with a non-zero acceleration.
