Instructions: For Part 1, answer the Pre-Lab questions before performing your investigation in the lesson. Then, follow the guidelines in the lesson to gather data for Part 1. For Part 2, use the results of your lab activity to answer the questions. Use complete sentences in both parts. Part 1: The Lab Pre-Lab Questions 1. List the four fundamental forces in order of strongest to weakest. 2. Compare the magnitude and range of gravity with the magnitude and range of electromagnetic force. 3. Consider the mass of the objects in the activity (small ball, large ball, feather) and compare the gravitational force between them and the Earth. If distance is the same, which object would you expect to experience the greatest gravitational attraction with the Earth? Support your response with reasoning. Your Investigation 4. State your hypothesis. Hypothesis: 5. Identify the variables in your experiment. Independent variable: Dependent variable: Controlled variables: Data and Observations
