APPLYING THE SCIENCE PRACTICES: FINDING ACCELERATION DUE TO GRAVITY
While it is well established that the acceleration due to gravity is quite nearly 9.8 \(\mathrm{m/s}^2\) at all locations on Earth, you can verify this for yourself with some basic materials. Your task is to find the acceleration due to gravity at your location. Achieving an acceleration of precisely 9.8 \(\mathrm{m/s}^2\) will be difficult.
However, with good preparation and attention to detail, you should be able to get close. Before you begin working, consider the following questions. Your task is to find the acceleration due to gravity at your location. Achieving an acceleration of precisely 9.8 \(\mathrm{m/s}^2\) will be difficult. However, with good preparation and attention to detail, you should be able to get close. Before you begin working, consider the following questions.
- What measurements will you need to take in order to find the acceleration due to gravity?
- What relationships and equations found in this chapter may be useful in calculating the acceleration?
- What variables will you need to hold constant?
- What materials will you use to record your measurements?
Upon completing these four questions, record your procedure. Once recorded, you may carry out the experiment. If you find that your experiment cannot be carried out, you may revise your procedure.
Once you have found your experimental acceleration, compare it to the assumed value of 9.8 \(\mathrm{m/s}^2\). If error exists, what were the likely sources of this error? How could you change your procedure in order to improve the accuracy of your findings?
