AP Physics 1 Bonus WS2 - Experimental Design For all of the following questions, you have access to any and all apparatus you have used throughout the school year unless specifically constrained by the problem otherwise. In your explanations for each problem or scenario below be sure to: Specify what data specifically you will be measuring in your experiment. Make sure to note any values that will need to be kept fixed. Describe the procedure necessary to obtain your data clearly, thoroughly, and concisely. Make sure to describe what materials will be necessary to conduct the experiment and sketch a picture of the experimental setup. Describe how the data you obtain in your experiment will be used to achieve the goal of the problem. . Make references to graphs, equations, etc. as needed. If a graph needs linearization in order to be useful, describe what must be done to the data and how the linearized version of the graph achieves the goal of the problem. Problems 1-4: Imagine you are on a planet with an unknown gravitational field strength g. The planet's mass is unknown, as is its radius. 1. Design an experiment to find g for the planet using either a motion detector or two photogates. 2. Design an experiment to find g for the planet using an ideal spring. 3. Design an experiment to find g for the planet using a pendulum. 4. Design an experiment to find g for the planet using a stopwatch. 5. A new exoplanet has been discovered orbiting a nearby star. The exoplanet is large enough compared to the star that it affects the observed luminosity of the star when it passes directly between the star and Earth. You may assume the star has a mass M and that the exoplanet has a circular orbit around the star. Explain how you could determine the distance the exoplanet is from the star
