In this experiment we tied a cart to a hanging mass and measured the velocity as it passed through a gate, and recorded the mass of the cart. I calculated the potential and kinetic energy of the hanging mass and when I subtracted the potential from the kinetic, I got a negative number. Does this mean that energy was lost? Do these results make sense? Please let me know if I wasn’t descriptive enough of the scenario!

Here is what I did for trial 1 (all of the units are what they need to be for the formula to work):
