Mechanical Energy Conservation, Part II
The default angular positions are for the "0 - 1 - 2 and back" procedure. They may be reset if necessary.
Calculation Procedure
Enter the average calculated moment of inertia for your table and the radius of the pulley.
In each row, enter the values for the hanging mass and the corresponding two times.
Click "Calculate Step 1".
Use the displayed data to calculate the three values of the mechanical energy in the first row.
Enter these values in the last three columns.
Click "Calculate Step 2".
If the values for the mechanical energies that you have entered are correct, you are done. Otherwise, recalculate and re-enter.
Note: The calculation assumes that the potential energy is zero at the lowest position of the hanging mass.
