1. The problem statement, all variables and given/known data I am writing a lab report and I need to calculate the uncertainty error for Gravitational Potential Energy and Kinetic Energy. The Professor told us that the margin of uncertainty for time is +- 0.025 seconds, margin for height is +- 0.001 meters, margin for mass is +-0.001 kg, margin for velocity is +- 0.2. 2. Relevant equations Eg= mgh Ek=1/2 mv^2 3. The attempt at a solution I do not understand how to calculate the margin of error for either equations with the given variables. Any Help Is Appreciated.
