Solving a Spring Compression Puzzle: Work Done by Gravity

Click For Summary

Homework Help Overview

The discussion revolves around a physics problem involving a block dropped onto a vertical spring, focusing on the work done by gravitational forces and the spring during compression. The subject area includes concepts of mechanics, specifically energy transfer and work in the context of springs.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • The original poster seeks guidance on how to calculate the work done by gravity on the block. Subsequent posts explore the calculation of work done by the spring and question the relationship between the work done by gravity and the work done by the spring. Participants discuss the definition of work and its implications in this context.

Discussion Status

The discussion is ongoing, with participants exploring different aspects of the problem. Some have provided calculations and definitions, while others are questioning the correctness of these calculations and the relationships between the forces involved.

Contextual Notes

There appears to be some uncertainty regarding the definitions and calculations of work, as well as the assumptions about energy transfer in the system. The original poster and others are navigating these concepts without reaching a definitive conclusion.

Spring Question!

A 250g block is dropped onto a relaxed vertical spring that has a spring constant of 2.5N/cm. The block becomes attached to the spring compresses the spring 12 cm before momentarily stoppoing.
While the spring is being compressed, what work is done on the block by
(a)The gravitational forces on it?

Can anyone tell me where to start?
 
Physics news on Phys.org
(b)what work is done on the block by the spring?

is it this simple:

Ws = -0.5k(x^2)

Ws = -0.018 Joules

?

shouldn't the work done by gravity equal the work done by the spring?

What is the usual definition of work?
 
energy transferred to or from an object via a force acting on the object. energy transferred from the object is negative..energy transferred to the object is positive.

Ok..So is my answer Correct
?
 
??
Anyone??
