Mechanical Energy Conservation, Part I

Student Name  

x1 (m) x2 (m) Mglider (kg)
mhang. (kg) t1 (s) t2 (s) v02 (m2/s2) v12 (m2/s2) v22 (m2/s2) ME0 (J) ME1 (J) ME2 (J)

The default angular positions are for the "negative acceleration" fence. They may be reset if necessary.

Calculation Procedure

  • Enter the mass of the glider for your table.
  • 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.
