PHY-102: Motion Exercises

PHY-102: Motion Exercises Complete the following exercises. Jane is collecting data for a ball rolling down a hill. She measures out a set of different distances and then proceeds to use a stopwatch to find the time it takes the ball to roll each distance. What is the independent variable in her experiment? The independent variable is represented by the ball. What is the dependent variable in her experiment? The Dependent variable is represented by the stopwatch. Give one control variable for her experiment. The control variable represents the distance. Consider an experiment where you drop an object. a. Briefly describe your proposed experiment. (Make sure it is controlled). I will drop a basketball off the second floor of my apartment building. b. What would be the independent variable for your experiment? The independent variable would be the basketball. c. What would be the dependent variable for your experiment? Would be the second floor distance of the drop. d. Give one control variable for your experiment. The Height of the drop. 2. Consider a freely falling object. a. What is the acceleration (in m/s2) after 5 seconds of fall? 9.8 m/s2 b. What is the acceleration (in m/s2) after 10 seconds of fall? 9.8 m/s2 c. What is the velocity (in m/s) after 5 seconds of fall?98m/s d. What is the velocity (in m/s) of 10 seconds of fall?98m/s
