Week 13 Online Lab: Torque and Moment of Inertia Gizmo
Explore Learning Gizmo: Torque and Moment of Inertia
For this assignment, you'll use a Gizmo at the Explore Learning web site.
Before you begin:
Be sure you have read the assigned reading for the week.
You may want to print this document so that you can note observations as you work
with the gizmo. Later, you can type your answers into the Word document and upload it
with this assignment form.
All questions to answer are contained in this document. You don’t need to answer
any questions at the Explore Learning site.
This lab has a Prior Knowledge piece, a Warm-Up piece, and Activity A, B, & C with an
Extra Credit Opportunity.
You must answer in a different colored font (-1 point)
FINDING THE GIZMO
Follow these steps to find the Gizmo:
Go to the Explore Learning website: http://www.explorelearning.com/.
If you have not yet enrolled in the class -- In the upper right hand corner, click on Enroll
in a Class.
The class code you need is 6FZRUV6SEM (note - these are all capital letters).
Click on Continue.
If you have used the Explore Learning site before you should be able to log in using your
MNOHS username and password (for example, mnohs10ajones / piano227). If you
have never used Explore Learning before, you’ll need to register using your MNOHS
username and password with the class code. In other words, the class code is only
needed once!
Once inside the Physics course, look for the Gizmo called Torque and Moment of
Inertia and click on Launch Gizmo.

, 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: He should sit
more in the middle of the see saw to
distribute the weight evenly.
Gizmo Warm-up
The Torque and Moment of Inertia Gizmo™ shows a see-saw,
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,
making sure the weight of the object A is greater than the weight of object B.
3. Can you create a scenario in which object A perfectly balances object B? Yes
Explain: Making sure that the two weights equal one another and are the same
distance apart.
