In this Virtual Lab you will investigate the relationship between mass, acceleration, and force by experimenting with falling objects of various masses under a range of gravitational conditions. 1. Click the arrow under Location 1 and select a planet to test. Click the arrow under Object 1 and select an object to test. Repeat with Location 2 using the SAME object. 2. Click the Drop button and observe the two objects as they fall. Click the Drop button again to see them fall again. The lines following a falling object indicate the object’s relative position during each second of acceleration. 3. Using the mass and acceleration data displayed on the monitors, calculate the gravitational force (weight) of both locations. (F = M X A) Record your results in the table. 4. Repeat the above steps two more times with other objects and locations. Click the Reset button to clear the screen. Test
