* The blocks were put together with the string between the two blocks and they were squeezed together using the clamps jaws. The mass suspension should be friction free so that wood blocks are the used to provide string suspension. * The clamp was attached to the ring stand so that it can freely hold the string. Two small pieces of wood that can be closed in the jaws of the clamp The apparatus used in the experiment include When several measurements of T2 are graphed with different values of L we shall be in a position of experimentally determining the constant of proportionality and acceleration due to gravity g. From the formula it implies that T2 should be proportional to L and constant of proportionality is 4Ï€2/g. The relation between the length and the period is given by the formula T=2Ï€L/g whereby T is the period of oscillation, g is the gravitational force, and L is the length of the string (Psillos & Niedderer, 2002). It is then suspended using a stand the mass is the released with an angle to the vertical and the mass will then make oscillation in a plane. It is made up of a mass m suspended using a string of a certain length. A simple pendulum is a simple experiment that can be easily performed in a lab by students. In this experiment we shall measure the force of gravity g using a simple pendulum. In a situation where there is no air resistance for example in a vacuum two different objects of different masses for example a paper and cannonball when released from the same height they will hit the ground at the same time. Acceleration due to gravity is involved in the oscillation of the mass the universal accepted g is 9.8 ms2.įor over a long period of time, acceleration due to gravity has been known to be constant irrespective of the mass of the object (An OER from Textbook Equity, 2014). The time it takes to complete one oscillation does not depend on the suspended mass or the angle to the vertical in which the mass is released. Well known scientist Galileo was the first person to observe that the time taken by a simple pendulum to swing to and fro over a certain distance depends only on the length of the string that is attached to the mass (Muncaster, 2003). Such kind of oscillatory motion is known as simple harmonic motion. The movement of the pendulum suspended material represents period motion that was used long time to measure time (Muncaster, 2003). ![]() An example of such thing is a simple pendulum. In nature several things wiggle in periodic fashion, in other words they vibrate. By drawing a graph using the values of T2 and L and using the formula T=2Ï€L/g we found that the acceleration due to gravity is 10.39 ms2. For different lengths and fixed angle, evidence of a linear relationship between period T2 and length L is observed. In this experiment the time of 10 oscillations of different lengths of a string attached to the suspended mass was measured, the angle in which the pendulum was left to swing was kept constant. Calibration equipment is a breeze with that feature.Determining gravity acceleration using a simple pendulum I really like moving the mouse pointer to a position and having the Time and Voltage display the values at that point. We were a bit hesitant at first … but it worked flawlessly, and everybody is now out shopping for PicoScopes! T Lövskog Rather than webcam our benchtop scope screen, it was suggested we use a PicoScope to share waveforms via screen share. So simple to use & beats any other I have ever used hands down. Since the included software is really stable, this type of device is a great tool for great tasks! Helmut SchoettnerĪ superb piece of equipment worth its weight in gold Nigel Clinch Perfect Partner for Development of Encoder controlled Stepper Motor Actuators. If I could give 6 stars for customer service - I would do so. Customer service gave me first class service. I had a weird problem - it did not work on one of my PC’s. ![]() PicoLog TC-08: This is a very nice unit that works consistently and reliably. ![]() We have been using Picoscope 6404D for quite some time, and are amazed by its accuracy and powerful emulations while working with numerous signal evaluations. This made my decision much easier when I was looking to buy an USB scope. Not many USB scopes works on Win & Mac & Linux too, so that proves me that guys from Pico really cares about us, customers. Storage of waveforms on my Laptop is very easy allowing me to quickly email waveforms to my Colleagues. I travel abroad so this has been ideal due to its physical size. I have been using my 4224 PicoScope for years. Superb kit, superb support, what more can I say. The kit (2408B) is of obvious quality, easy to setup and calibrate and the free to download software has a reasonable learning curve.
