Investigating “g” On Other Planets Virtual Lab Click on the link: http://www.glencoe.com/sites/common_assets/science/virtual_labs/E25/E25.html to complete this lab activity. Discussion: A __________is any push or pull on an object and is measured in Newtons. ______________ forces are forces that are equal and opposite. ________________forces can cause a change in motion. According to Newton’s 2nd Law of Motion, if a net force is applied to an object, the object will __________ in the direction of the force. ________is the amount of matter in an object and it is measured in kilograms. ____________________________is the rate of change in velocity that can be caused by speeding up, slowing down, or changing the direction of the motion and it is measured in m/s/s. All objects on Earth fall at an acceleration rate of _______m/s/s in the absence of friction or air resistance. Procedure 1. Choose a planet under Location 1 and a different location under Location 2 then choose an object that is the same for both locations. Record your locations and your object in the data table. 2. Record the rate of acceleration for each location and the object’s mass in the data table. 3. Click the drop button & observe the object’s fall. The green lines indicate the object’s position at each second. 4. Calculate the force of the objects (weight) using Force = Mass x Acceleration. Record in your data table. 5. Repeat steps 1 – 4 for another object in the same locations. 6. Repeat steps 1 – 4 for the object in step 5 but with two different locations. Data Table: Test Location Object Acceleration (m/s/s) Mass of Object (kg) Force or Weight (N) Conclusion 1. How is Newton’s Second Law related to gravity? 2. How does the force of gravity affect the rate of acceleration? 3. Describe how motion is affected when the same object is dropped on different planets. 4. Describe how motion is affected if two objects of different masses are dropped on the same planet. 5. According to your data, what is the relationship between mass and weight?
