Homework Help Overview

The discussion revolves around the concept of acceleration in relation to speed, specifically whether a particle can accelerate without changing its speed. The subject area is physics, focusing on motion and acceleration.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the idea of uniform circular motion as an example where acceleration occurs without a change in speed. Questions arise regarding the definitions of speed and velocity, and the implications of circular motion on these concepts.

Discussion Status

The discussion is active, with participants sharing examples and clarifying terms. There is a recognition of the distinction between speed and velocity, although some participants express confusion about these concepts. Guidance has been offered regarding uniform circular motion, but there is no explicit consensus on the definitions being used.

Contextual Notes

Some participants question the terminology used, particularly the difference between speed and velocity, and how it applies to circular motion. There is also a light-hearted acknowledgment of potential misunderstandings in the discussion.

Homework Statement



It is possible for a particle to accelerate without changing its speed.

True or False?


Homework Equations



I don't think there is any except average acceleration equation


The Attempt at a Solution



I am thinking False because Acceleration depends on velocity vector

Think of uniform circular motion
 
lol i am lost, wats uniform circular motion?
 
An example...

A car going around a circular track at the same velocity.
 
oh i get it, so if the car goes in a circle, it accelerates but it doesn't actually increase its speed right?
 
Yes that's right, because the car's direction is always at a tangent to the circle, hence it accelerates at a tangent, but due to the centripetal force, it stays in a circular motion
 
thankyou

No problem

Just to clear up any possible misinterpretation, I believe Fonseka meant to write: A car going around a circular track at the same speed.

It is not possible to go around a circular track at constant velocity.

Yep, can't believe I said velocity there :O 100 push ups

lol, it would be hilarious if a teacher did that infront of a classroom for saying the wrong thing
