(1) The energy that an object has because it is lifted is called gravitational potential energy, so when the barbell is lifted and stays on the top of the head, it has gravitational potential energy;

(2)∫G = mg，

∴ Ping Li's snatch score is103kg: w1= g1h = m1GH =103kg× 9.8n/kg×1.8m =

Work done in the clean and jerk w2 = g2h = m2gh =127kg× 9.8n/kg×1.8m = 2240.28j.

Then she did work twice: w1+w2 =181.692j+2240.28j = 2421.972j.

So the answer is: gravity potential; 242 1.972.
