When you release an object near the surface of the Earth, it falls. In the absence ofair resistance, the object, regardless of mass, will fall downward with an acceleration of 9.8 ml '1 s . In this assignment, you must carry out an investigation into the nonuniform motion experienced by two falling objects. For any investigation, there is a specific method to follow, often called the Scientific Method. It divides an investigation into seven parts: Purpose: What do we want to accomplish in this investigation? Hypothesis: What do we think will happen? What do we predict the result to be? Materials: What apparatus will we use to complete this investigation? Procedure: What method will we follow in order to test our hypothesis? Observations: What did we observe during the investigation? Analysis: What can we deduce from our observations? Conclusion: Was our hypothesis correct? What did we discover by doing this investigation? Forthis investigation, you will be prompted for each part, and even given some of the wording. In this task, anything in italics must be answered or completed; anything in regular type can be copied directly. As the course continues and we do more investigations, you will be expected to complete more and more ofthe process on your own. Check with your teacher if you have any questions. Purpose: The purpose ofthis investigation is to observe a falling object, a car falling offa cliff, to determine its acceleration, and compare that value to the accepted value of gravitational acceleration here on Earth. Hypothesis: The accepted value ofgravitational acceleration on Earth is 9.8 mi's2 [down]. What do you think the acceleration ofthe car will be? Why do yOJ think it will be that? Materials: For this investigation, you will collect data from a simulation. No other materials are needed. Observations: Create a table of values for time (t) in seconds and position (J) In metres. 31-5 Analysis: \"Construct a positiontime graph using your data. Remember that a good graph has a cleartltle and clearly labeled axes (with quantity being measured and unit of measurement). ajAccording to your positiontime graph, what type of motion did the object undergo? \"-3 \"5 biUse your positiontime graph to determine the instantaneous velocity at a time of your choice. Clearly show the procedure and calculation. 14 56 SIS 1.Construct a velocitytime graph using your data. Draw the line of best t. Calculate the slope ofthe line. What does the slope represent? 2.The accepted value of acceleration due to gravity close to the Earth's surface is 9.8 mfs2 [down]. Determine the percentage deviation of your value of acceleration, using the following formula: % deviation : [(measured value accepted value) I accepted value] x 100% Bit the value is not 9.8 mils:2 [down], then there must be other forces at work, apart from gravity. What other forces might be acting on the car as it falls? Justify your thinking. Conclusion: Is a car falling offa cliff an example of uniform motion or non-uniform motion? How do you Know? What value of acceleration did you nd? What was the percent deviation? Was your hypothesis valid? Why might the value of acceleration be different than the accepted value of 9.8 ml 52 [down]
