Student Exploration: Torque and Moment of Inertia Vocabulary: angular acceleration, fulcrum, lever, moment of inertia, Newton’s second law, torque, weight Prior Knowledge Question (Do this BEFORE... using the Gizmo.) During recess, Tom and his little sister Marcie want to play on the see-saw. Tom is quite a bit heavier than Marcie. Where should they sit so the see-saw is balanced? Sketch their positions on the image below. Explain your reasoning: Tom should sit more towards the middle of the see saw the distribute weight. Gizmo Warm-up The Torque and Moment of Inertia Gizmo™ shows a seesaw, which is a type of lever. The see-saw can hold up to eight objects. To begin, check that the Number of objects is 2. Check that the mass of object A is 1.0 kg and the mass of object B is 2.0 kg. The two objects are equidistant from the triangular fulcrum that supports the lever. 1. Click Release. What happens? The see saw falls towards the right side 2. Click Reset. Without changing the masses, experiment with different positions of objects A and B by dragging them around. Can you create a scenario in which object A goes down and object B goes up? Yes, just make sure the weight of object is greater than that of object B. 3. Can you create a scenario in which object A perfectly balances object B? Yes, make sure the two weights equal one another and are the same distance apart.

Turn on Show ruler.  Check that object A is 1.0 kg and B is 2.0 kg. Question: How can you use a light object to balance a heavy object? 1. Explore: Experiment with the Gizmo to see how you can balance a heavy object with a light object. What do you notice about the distances of each object from the fulcrum? Make sure the object with the smaller weight is closer to the outside and the heavier object is closer to the center. 2. Gather data: For each mass and location of object A, find a location for object B so it perfectly balances object A. You can change the mass of object A by typing the mass into the text box and hitting “Enter” on your keyboard. Leave the mass of object B the same (1 kg) in each experiment. Include all units in the table. Object A mass Object A location Object B mass Object B location Object A m × d Object B m × d 1.0 kg -0.4 m 1.0 kg .4 -.4 .4 2.0 kg -0.4 m 1.0 kg .8 -.8 .8 3.0 kg -0.4 m 1.0 kg 1.2 -1.2 1.2 4.0 kg -0.4 m 1.0 kg 1.6 -1.6 1.6 3. Analyze: What patterns do you notice in your data? The two objects are the same distance [Show More]
