INSTRUCTIONS: Open up the Gravity Force Lab Basics simulation on the PhET website. https://phet.colorado.edu/sims/html/gravity-force-lab-basics/latest/gravity-force-lab-basics_en.html 1. Get familiar with the simulation by moving the figures back and forth as well as changing the mass of the spheres. 2. Underline the different variables that can be found in this simulation. Distance between figures Mass of the spheres Force Size of the figures Strength of the figures Size of spheres 3. What do you think the size of the arrows on top of each sphere represent? 4. Pick a variable to manipulate (the independent variable). Summarize what you changed and what happened in the table below: Manipulated (Independent) Variable Dependent Variable 5. Change a different variable and summarize what happens in the table below: Manipulated (Independent) Variable Dependent Variable Test your understanding: True or False State the correct answer and provide your reasoning 6. Gravity is a force that can be changed. T/F 7. The bigger an object is, the smaller the force of gravity. T/F 8. As one object gets closer to another object, the force of gravity will increase. T/F 9. The Sun has a greater gravitational force than Jupiter. T/F
