概要

TLDRIn this video, Dr. Tom Dixon outlines the upcoming lab on linear oscillatory motion, which consists of four parts: an introduction, important theory, lab procedures, and tips for success. The lab's goal is to measure the spring constant using two methods: a direct method involving mass addition and deflection measurement, and a second method using a motion detector to analyze oscillatory motion. Key theoretical concepts such as Hooke's Law and the relationship between angular frequency and the spring constant will be discussed to prepare students for the lab.

    Dr. Tom Dixon introduces the lab for week n on linear oscillatory motion, outlining the video structure which includes an introduction, theory, lab procedures, and tips. The lab aims to measure the spring constant using two methods: a direct method involving mass and deflection, and a motion-based method using a motion detector to analyze oscillation periods. He emphasizes the importance of understanding the theory behind these methods, including Hooke's Law and the relationship between motion period and spring constant, and encourages viewers to engage with the upcoming videos for a comprehensive understanding.

  • 00:00:00
    hi everyone Dr Tom Dixon here from my
  • 00:00:03
    office studio uh and in this video I'm
  • 00:00:05
    going to be going over everything that
  • 00:00:07
    you'll need to know for the lab in week
  • 00:00:09
    n entitled linear illary motion now this
  • 00:00:13
    preab is going to consist of four parts
  • 00:00:15
    the first part is what you're watching
  • 00:00:16
    now just a general intro what are you
  • 00:00:18
    going to be doing in the lab just to
  • 00:00:19
    kind of make sure you understand what to
  • 00:00:21
    expect in the second part of the video
  • 00:00:23
    I'm going to be going over some of the
  • 00:00:24
    important Theory so I'm going to be
  • 00:00:26
    swapping to a whiteboard or a digital
  • 00:00:28
    whiteboard I'm going to go over some of
  • 00:00:30
    the important Theory covering really
  • 00:00:32
    what you need to know in the lab of
  • 00:00:34
    course you should and hopefully have
  • 00:00:36
    learned it in your lectures but I will
  • 00:00:38
    go through it just in case cuz I want to
  • 00:00:39
    make sure that everyone's prepared and
  • 00:00:41
    ready to succeed in the third video
  • 00:00:44
    we're going to be going over exactly how
  • 00:00:46
    to do the lab so I'm going to be going
  • 00:00:47
    through all the pieces of equipment
  • 00:00:49
    exactly how they function how to open
  • 00:00:50
    all the software how to operate
  • 00:00:52
    everything and then finally in the
  • 00:00:54
    fourth video going to go through a few
  • 00:00:56
    tips and tricks and maybe some
  • 00:00:57
    extensions if you're interested in going
  • 00:01:00
    a bit further in your laboratory Journey
  • 00:01:02
    so the purpose of the lab in week n is
  • 00:01:05
    to measure the spring constant the
  • 00:01:08
    stiffness of a spring via two different
  • 00:01:11
    methods the first method is what we're
  • 00:01:13
    going to call Direct you're going to be
  • 00:01:16
    adding masses to the spring and slowly
  • 00:01:19
    letting it hang down measuring the
  • 00:01:21
    deflection as a function of mass which
  • 00:01:23
    you can then convert to a function of
  • 00:01:25
    force and find K the spring constant of
  • 00:01:29
    the spring
  • 00:01:30
    the second method you're going to be
  • 00:01:31
    using involves setting the spring in
  • 00:01:34
    motion which is why the lab is called
  • 00:01:35
    linear oscillatory motion and you're
  • 00:01:37
    going to be using one of these lab quest
  • 00:01:40
    um motion detector twos by Veria to
  • 00:01:43
    detect the period of the motion and use
  • 00:01:46
    that to solve for K now of course if you
  • 00:01:49
    don't understand how the period of the
  • 00:01:51
    motion can relate to the spring constant
  • 00:01:54
    we're going to be going over that in the
  • 00:01:55
    theory which is after this video if you
  • 00:01:58
    are feeling confident on it you should
  • 00:02:00
    still check out the theory because the
  • 00:02:02
    prelab in your books I.E the stuff that
  • 00:02:04
    you have to write down does contain a
  • 00:02:07
    fairly non insubstantial amount of
  • 00:02:11
    derivations and those derivations are
  • 00:02:13
    actually quite important it's taking a
  • 00:02:14
    free body diagram and really arriving at
  • 00:02:17
    a final answer for something so I hope
  • 00:02:21
    you watch the rest of these videos and
  • 00:02:23
    enjoy I'm going to be going through in
  • 00:02:25
    the next video some important Theory so
  • 00:02:27
    we're going to be covering some of the
  • 00:02:28
    stuff that you would have seen in
  • 00:02:29
    lectures such as hooks law what is a
  • 00:02:32
    hook in Spring what isn't a hook in
  • 00:02:34
    Spring we're going to be talking about
  • 00:02:35
    linear oscillation we're going to be
  • 00:02:37
    talking about deriving the sinusoidal
  • 00:02:40
    relationship of a um of an oscillator or
  • 00:02:43
    the sinusoidal kind of uh governing
  • 00:02:45
    equation I guess one could say of an
  • 00:02:47
    oscillator and also how to find the
  • 00:02:49
    spring constant K from the stiffness
  • 00:02:52
    sorry from the
  • 00:02:55
    uh angular frequency Omega I'm not
  • 00:02:58
    editing that uh so thank you for
  • 00:03:00
    watching I hope you are prepared excited
  • 00:03:03
    and happy and I'll see you in the next
  • 00:03:04
