Planning and Designing a lab on Coupled pendulums

  1. Dec 23, 2012 #1
    My teacher told me plan and design about 4 labs, okay the thing is I'm not sure about the layout of P/D for physics labs.

    I know there has to be expected results, I'm confused I don't know what to put there.

    My teacher gave me a lab manual to try and guide me okay, in the book at the end of the method for this Coupled Pendulum lab it asks me to plot a graph, how can i do that without values?

    What should I do?

    You could calculate how the values should look like?

    Hmm... but how would I know what they should be near to ?

    Which type of graph do you try to plot?
    If you don't know parameters of your coupled pendulums, find some plausible numbers. Like a length of ~50cm, a harmonic coupling with ~5% of the strength of the individual pendulums, some weaker damping (like <1%/cycle or even 0) or similar values. Solve the system, plot the time-evolution of the system.

    Oh thank you, one more thing could you tell me the layout of a p/d lab my teacher didn't tell me. I know you're supposed have a hypothesis and expected results and so on.

    I don't understand what you are looking for.

    I mean like for a p/d lab you would have

    -Title
    -Aim
    -Hypothesis
    -Apparatus/Materials
    -Variables
    -Procedure
    -Data Collected
    -Treatment of Data
    -Discussion (limitations, sources of errors)

    but is this all?
