Considering pendulums, their practical value is apparent since they are used as parts of clocks, metronomes, and seismometers. Finding Acceleration Due to Gravity Using Ball Drop Method Aim: To calculate the acceleration due to gravity by dropping a ball from a certain distance and. The expected results of this lab include: the acceleration due to gravity being 9.8m/s2, coefficient of kinetic friction being 0 due to the friction-less track, and the tension in the string being equal to the weight of the hanger. For example, the power of gravity allows artificial satellites to orbit around Earth without falling as their mass is calculated regarding acceleration due to gravity. The acceleration of the hanger will then be measured using the Vernier motion detector. The force on a free falling object is its weight defined by mass x. In this experiment, we measure the time it takes a cart to travel a distance down a frictionless incline and use this to determine the acceleration of. If materials of different weights, size, or shape had been used in the performed lab exercise, the results would still be the same because the physical force of gravity is constant for all falling objects.Īnother significant aspect of this lab exercise is that it was not merely an academic exercise because the concept of acceleration due to gravity is highly applicable in practice. The equation that shows this is Fma (force on body mass of body x acceleration of body). As acceleration due to gravity is the physical constant, it does not matter what shape and size are the falling objects (any other thing could be used instead of the paper strip), and thus both methods give the same result, despite that the input data differs. Now looking at Equation (1) and equating F to the gravitational force (Fg), we. The acceleration can be calculated by the formula a (2d)/t2. This force (measured at the Earths surface) is called the weight of the object. Required Equipment Ticker timer Ticker timer tape 100-200 g mass Discussion A mass attached to one end of the a ticker tape and is allowed to drop through. When acceleration is constant, the following equations may be used: 02. It is also highly important to emphasize why the same quantity derived from two different activities. The purpose of this lab is to measure the acceleration due to gravity of a falling object. Doc Fizzix Lab Activity Finding Gravity Finding Gravity Lab 1.4 Chapter 1 Linear Motion Purpose The purpose of this experiment is to determine the acceleration due to gravity. Overall the free falling object method was a fair and simple experiment to determine the acceleration due to gravity. Once velocities are known at definite times, we can find the average acceleration by using the definition t v a.
