Unformatted text preview: total work done on the system. 9. From your calculated uncertainty in kinetic energy and potential energy, calculate the uncertainty in the total energy E tot = KE + PE 10. Create columns for the maximum and minimum kinetic energy, potential energy, total energy and work respectively by adding and subtracting your uncertainty in these quantities to the values you measured. 11. Plot the measured range (ie. the maximum and minimum) of the total kinetic energy, the potential energy of the falling mass and the total energy as a function of Δ x . Is the total energy constant within the experimental uncertainty? 12. Plot the measured range (ie. the maximum and minimum) work done by gravity and the measured range (ie. the maximum and minimum) of the change in total kinetic energy versus Δ x . Do they agree within the experimental uncertainty? 52...
