Fundamental Forces Worksheet 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. The strong nuclear force, the electromagnetic force, the weak nuclear force, gravity. 2. Compare the magnitude and range of gravity with the magnitude and range of electromagnetic force. Gravity is force of attraction between two objects The magnitude and range of gravity depends on the mass of the objects and their distance . Electromagnetic forces are the only forces that can both attract or repel each other. The electromagnetic force depends on the number turnings of the electromagnetic field and the current flowing through it. The force also has a very long rage its attraction and repulsion cannot reach over as long a distance as gravity's attraction. Your Investigation 4. State your hypothesis. Hypothesis: Yes, I think the feather will fall at the least rate and the big ball first small ball 2nd place 5. Identify the variables in your experiment. Independent variable: The objects used (small ball, large ball, feather) Dependent variable: Observations of gravity test trials Controlled variables: Distance between objects and mode (normal or vacuum) Data and Observations Unless Otherwise Noted All Content © 2022 Florida Virtual School.

6. Table 1: Gravity Test Trials Trial Objects Used Observations—Normal Mode Observations—Vacuum Mode 1 Big ball and small ball both balls hit the ground at virtually the same time. both objects hit the ground at the same time but slower rate. 2 feather and big ball the big ball hit the ground first both objects hit the ground at the same time but faster rate. 3 small ball and feather When the small ball and the feather are dropped at the same time, the small ball hits the ground first. both objects hit the ground at the same time but at faster time Part 2: Conclusion Data Analysis 7. Did the experiment support your hypothesis? Use data from your experiment to support your claim. No it did not support my hypothesis because they all dropped at different times. Both they small and big ball fell at the same rate in normal mode.Both objects hit the ground at the same time but at a slower rate in the vacuum mode.The big ball hit the ground before the feather in normal mode. All objects ihit the ground at same time but different speed. Unless Otherwise Noted All Content © 2022 Florida Virtual School. FlexPoint Education Cloud™ is a trademark of Florida Virtual School.
