    hey guyz ,
    i had a question about physics coursework.
    simple harmonic motion!!!
    would u recommend a simple pendulum or a mass-spring system???
    thx

    the mass spring system, as the pendulum is only an approximation to the SHM

    but what would be better a datalogger or using a protractor and stopclock???

    a datalogger would be so much better because it removes some significant sources of error, ie the human reflexes.

    thx so much!!!
    the most offputting thing about this practical wa sthe fact that the schools datalogger records the displacement in degrees !!!

    I fail to see how you could use a protractor with a mass on a spring unless you are going to study some rather complicated vertical and horizontal combined motion.

    But, I agree with elpaw...dataloggers are fantastic assuming you can get them to work properly. I would recommend that you had your datalogger connected to a computer while you are making your measurements so that you can see them on the screen. Also, plot graphs as you go along so that you can see that predicted relationships are being seen.

    thank you,
    that's exactly what i considered but my physics teacher didn't approve of it much, thus i doubted myself.

    Well, if its any consolation, Professors of physics in Cambridge tell us to do it that way so I think you should tell your teacher that. If he still thinks he knows best then...............

    I suppose, perhaps she wanted an easier option and that was the use of no information technology in the investigation
