Homework Help Overview

The discussion revolves around the relationship between power, work, and acceleration in the context of an object receiving power at a constant rate. Participants are exploring why the acceleration of the object is not constant despite the constant power input.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are examining the definitions of power and work, questioning how changes in energy relate to acceleration. Some are considering the implications of constant power on the object's acceleration and whether energy changes over time affect this relationship.

Discussion Status

The discussion is active, with participants sharing their thoughts on the relationship between power, work, and acceleration. There is an acknowledgment of assumptions, such as the condition of the object not reaching terminal velocity, and some participants are refining their understanding of the concepts involved.

Contextual Notes

Participants are navigating the definitions and implications of power and work, with a focus on how these relate to acceleration. There is an underlying assumption that the object is not at terminal velocity, which may influence the discussion.

Homework Statement


Power is being provided at a constant rate to an object. Suggest why the accelration of the object is not constant.


The Attempt at a Solution



power is defined as the rate of change of work

P=W/T

Power is changing with respect to time. This increases the work done by the object. Since work done=fs (f=ma)
The acceleration is not constant.

Are my points valid or wrong

Power is changing with respect to time.
Perhaps it would be better if you reworded your answer.
 
ok so energy is changing with respect to time ?

Much better :approve: This of course assumes that the object has not reached its terminal velocity.
 
since energy=work done
and workdone=fs
the acceleration of the object is not constant
