Now, after having the availability of microprocessors, sensors and data analysis softwares, it is an interesting task to develop an experimental setup to determine the value of gravitational acceleration for a freely falling body with the aid of modern data acquisition and data analysis tools. From these experiments scientists have been able to accurately determine the value of g which came out to be 9.8 m/s 2. In history, many experiments have been performed to determine the value of g, especially the famous experiment of Italian scientist Galileo which he performed at the leaning tower of Pisa, Italy. Velocity of the freely falling object increases at a constant rate which is termed as acceleration due to gravity ( g). Due to this force every object in our daily life falls downwards when released from a height. Earth attracts every object towards its center with a force which is given by Newton’s law of universal gravitation. Without gravity, we would have no weight and would not be able to walk around on the earth. On Earth, gravity gives weight to physical objects, and is also necessary for our motion on the surface of the earth. Gravity has an infinite range, although its effects become weaker as objects get further away. The gravitational attraction of the original gaseous matter present in the Universe caused it to begin coalescing and forming stars and caused the stars to group together into galaxies, so gravity is responsible for many of the large-scale structures in the Universe. Īmong the basic concepts of physics, gravity or gravitation is of utmost importance which is a natural phenomenon by which all things having mass (including planets, stars, galaxies, and even light) are attracted to (or gravitate toward) one another. Sari who prepared an experimental setup for the calculation of coefficients of friction by the movement of a wooden block on an inclined plan. Therefore, Arduino UNO can provide an easy way to automate and improve various physics lab experiments. The board can be powered by the USB cable or by an external 9 volts battery, though it accepts voltages between 7 and 20 volts and is programmable with Arduino IDE (Integrated Development Environment) computer language/software. The simplest and easy to use circuit board available is the Arduino UNO which is equipped with sets of digital and analog input/output pins that may be interfaced to various sensors, expansion boards or other circuits.
Common examples of such devices intended for beginner hobbyists include simple robots, automated path finding vehicles, thermostats and motion detectors. One such bridge between the electronic and mechanical gadgets is made by Arduino which began in 2005 as a tool for students at the Interaction Design Institute Ivrea, Italy, aiming to provide a low-cost and easy way for both students and professionals to create devices that interact with the environment using various types of sensors and actuators. Moreover, students will get exposure to the practical use of modern technology. This will not only reduce time needed for data acquisition but will also increase precision and accuracy of the data. that if the general labs could be equipped with microprocessors and mobile data collection tools, the trend of working in lab will be directed more toward better data analyses instead of spending a lot of time in data collection. In a recent study, it is proposed by Chen et al.

Manual ways to record readings are being used which consume a lot of time and are less accurate. One important problem in School and High School labs (especially in developing countries) is unavailability of modern devices to acquire data.

Hardware and software prepared for the experiment are sufficient to examine movement of ordinary objects during free fall, therefore the experiment can be easily settled in a laboratory for the purpose of learning and teaching. After repeated experiments, value of gravitational acceleration was found to be 9.805 m/s2. The shape of the distance-time graphs obtained from the experimental setup was in good agreement with the predicted graphs and the calculated values of g lie within the expected range. Acceleration during the free fall was then determined by applying the standard kinematic equations. Readings were taken at different intervals during the fall to obtain distance time curves. Experimental data on the free fall of a plastic box through the air was gathered with the help of an ultrasonic distance sensor (HC-SR04). \) rather than a rough estimate.In this study, a simple Arduino-based experiment was designed to examine the acceleration of the object during free fall and to calculate the value of “g” (acceleration due to gravity).
