Snowman asked:


I’m trying to workout how much work is done when swinging a kettlebell from between the legs to overhead height. The movement could be traced as a semi-circle on a straight line pretty much.
Any formula I could use to calculate the work done?
I’m not too clued up on these things yet.

Am I right in saying that the kinetic energy should equal the potential energy at rest?
As far as I understand it (using a 20kg Kb as an example starting at, let’s say, 30cm above the ground), potential energy would be

m.g.h = (20)(9.8)(.3)
= 58.8 Joules

Or am I barking up the wrong tree?
