SUMMARY

The discussion centers on the dynamics of a time-lapse photo depicting three pendulums at different angles. The pendulum in the middle is observed to be traveling at the greatest speed, prompting questions about the definition of "fastest" and the frame of reference for measurement. Participants emphasize the need for additional context, including the direction of movement and the observer's perspective, to accurately interpret the speed of each pendulum. The conversation highlights the complexities of motion analysis in pendulum systems.

PREREQUISITES
  • Understanding of pendulum mechanics

You have a Photo of a pendulum with three pendulums. One is at an angle to the right the second Is straight down and third is at an angle to the left. The pengulum in the middle is traveling the greatest speed but why is the third one traveling the fastest ?

That really doesn't make much sense. One pendulum with three pendulums?

Perhaps you mean a time-lapse photo showing one pendulum in three different positions? I think we need more context and a better description to be able to interpret your question.
 
Yea I meant a time laps photo sorry. If the one is the middle is traveling the greatest speed then wouldn't it also be traveling the fastest?

What is "fastest"? According to whom? Apparently we need more context. What is the frame of reference of the observer and the frame of reference of the pendulum?

Edit: Also, which direction is the pendulum moving in for each of the positions shown?

Can you post the photo? Use the UPOAD button.
