Homework Help Overview

The discussion revolves around the concept of acceleration in relation to constant velocity, exploring fundamental definitions in physics and calculus.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants discuss the relationship between constant velocity and acceleration, with some asserting that acceleration must be zero if velocity is constant. Questions about the meaning of derivatives and their relevance to the topic are also raised.

Discussion Status

There is an ongoing exploration of the definitions of acceleration and derivatives, with some participants providing clarifications. However, there is no explicit consensus on the necessity of derivatives for understanding the current topic.

Contextual Notes

Some participants suggest that the original poster may not have a background in calculus, which could affect their understanding of the concepts being discussed.

what is the acceleration of a certain car if the velocity is constant?? is it zero?
 
Physics news on Phys.org
The acceleration is the derivative of the velocity respect to time so if the velocity is constant, the acceleration would be 0 (m/s^2) (as the derivative of a constant is 0)
 
what's the meaning of derivative?

Velocity is speed in a straight line. If the velocity is constant, there is no change in velocity, which is what acceleration is, so acceleration is 0 by definition. (Unless your teacher is very sneaky and is talking about the acceleration due to gravity.)

Derivatives are not necessary for this level of physics. Apparently you haven't had calculus, yet.
