Honors: The Conservation of Energy Lab

Lab is a mini but have a good discussion of energy conservation, i.e. PE lost is KE gained. and make sure you compare the two not just say they are the same. Consider % difference. This is found from

(- delta PE - Delta KE)/(-Delta PE) x 100 (to get percent)

I'd say anything less than about 8 % was pretty good although I've seen some in the 1 % range in the past.

Note the last column should be - delta PE since delta PE is a negative number and you want subtract the KE from a positive number.
