Acceleration vs Time Graph in Simple Pendulum

Click For Summary

Homework Help Overview

The discussion revolves around the Acceleration vs Time graph of a simple pendulum, with participants exploring the nature of the graph and its relationship to other graphs such as Velocity vs Time. There is confusion regarding whether the graph should be straight lines or sinusoidal curves.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are questioning the shape of the Acceleration vs Time graph, with some suggesting it should be sinusoidal while others argue for straight lines. There is also discussion about the relationship between displacement, velocity, and acceleration in the context of simple harmonic motion.

Discussion Status

The conversation is ongoing, with participants expressing differing views on the nature of the graphs. Some guidance has been offered regarding the derivatives of displacement, but there is no consensus on the correct representation of the graphs.

Contextual Notes

Participants are referencing specific graphs and images to clarify their points, indicating a reliance on visual aids to support their arguments. There is an emphasis on understanding the relationships between the different types of motion and their graphical representations.

can anyone please explain
Acceleration vs Time Graph in Simple Pendulum ?
these would be straight lines but i don't know why
 
Physics news on Phys.org
The Acceleration vs Time graph would actually be a sinusoidal curve, not a straight line. Perhaps you were thinking of acceleration vs displacement. If so; start with the general displacement-time equation for a simple pendulum, use it to find an acceleration-time equation, and compare the two.
 
No its not sinusoidal , see the attached image , the third graph is Acceleration vs Time of Simple Pendulum ...why these are straight lines ?
and also see the second graph , why Velocity vs time is not sinusoidal but in Mass attached to spring it is Sinusoidal

A simple pendulum approximately exhibits simple harmonic motion. My guess is that your graphs were just very crude approximations for the time derivative of the first graph.
 
what do you mean ??
please just explain the 3rd graph
 
What is there I am meant to explain. I'm telling you it's not correct. How much thought have you even put into this? Do you understand that velocity and acceleration are the first and second time derivatives of displacement respectively. Do the graphs you drew reflect that?
 
So can you show the correct Graph please ??

and in this image can you tell me where the velocity,acceleration is zero and where it is maximum
