Question 2: Complete the error calculations
If the weight used in the experiment is having an uncertainty of 1.4± 0.01N, the initial height is measured, with an uncertainty of 50 ±0.05 cm and the final height with an uncertainty
of 25.3 + 0.05 cm. (Potential energies are calculated by the formula weight x height)
Calculate,
1. The absolute uncertainty in the calculated value of Initial Potential Energy (in Joules) =
2) The absolute uncertainty in the calculated value of Final Potential Energy (in Joules) =
Question 3: Conclusions
The energy due to position is the
