Graphing a spring mass collision with a wall

AI Thread Summary
The discussion focuses on creating a graph for a spring mass system that collides with a wall, specifically evaluating the "bounce" after release. The setup involves a mass compressed by a spring, which impacts a wall and bounces back multiple times before coming to rest. Key considerations include whether the graph should represent a vertical or horizontal motion and determining the coefficient of restitution, which is estimated to be around 0.60 for steel. The user clarified that this is not for schoolwork but for a design problem. Assistance in visualizing the setup through a sketch was also requested.

TL;DR Summary
Help determining a way to graph the bounce from a collision between a spring-mass system and a wall.
Hi, I'm looking for help making a graph/model for evaluating the "bounce" of a mass behind a spring that collides with a wall. The setup would include one simple spring mass system that is attached to a wall, and another wall which is closer to the mass than the spring's free length. The mass is pushed farthest back compressing the spring completely and then released. After release, it impacts the other fixed wall. Following this, the mass would theoretically bounce a small amount several times before coming to a rest (if the speed/force of the return is sufficiently high). What approach should I use to graph this response? Any help is greatly appreciated, thanks!

Welcome to the PF. :smile:

Vertical or horizontal? Coefficient of restitution of the mass hitting the wall?

Could you please attach a PDF file with a sketch of the setup to help clarify your question?

Also, is this for schoolwork? If so, I can move this thread to the schoolwork PF forums. Thanks. :smile:

Thanks for your response! Sorry, I really should've specified that, horizontal. In regards to the coefficient of restitution, I'm not sure how to determine that if this is purely analytical, I don't have any existing results to generate one. The part will likely be some form of steel, and steel bearings appear to bounce with a restitution coefficient of approximately 0.60. However, that is an extremely rough assumption. I added a picture. It's not for schoolwork, just a design problem I'm trying to figure out.

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
