Forces in Our Solar System Lab Report Introduction Gravity is the force of attraction that pulls objects toward the center of Earth and that holds the moon in orbit around Earth. Galileo was intere... sted in understanding gravity. He assumed all objects are subject to the same acceleration due to gravity. The objective of this lab assignment is to determine if objects with different masses fall at the same rate or varying rates in the presence of air and in a vacuum. Problem: What effect does Earth's gravitational force have on objects of different masses? Hypothesis: For your hypothesis, predict what will happen to the acceleration of objects in normal mode and vacuum mode. For example: If I drop two objects in normal mode, their acceleration to the ground will __reach the ground normally__________________. If I drop two objects in vacuum mode, their acceleration to the ground will ____increase exponentially_______________. Materials:  Gravity virtual lab activity Procedures: 1. Familiarize yourself with the virtual lab activity. 2. Using the virtual activity, choose two different objects from the upper left-hand corner (the feather, big ball, and small ball). 3. Drag your objects into Galileo’s hands and select “DROP.” Record your observations on Table 1. 4. Repeat three times with different combinations. 5. Select the “VACUUM MODE” and repeat steps 2 through 4 with the same objects you used in trials one through three. 6. Record your observations in Table 1. 7. Complete the Questions and Conclusion section of the lab report. Variables: For this investigation, list the independent, dependent, and controlled variables. Data and Observations: [Show More]
