Electrical to Wind Electrical 120 V .54 A Joule’s Law: P=I*V P= .54*120= 64.8W E=Pt E=64.8(10)= 648 Joules

Wind to PotentialWater Bottle Formula= mgh M= .105 Kg H= 7 in or .1778 m (.105)(9.8)(.1778)=

.183 J

Hammer Formula= mgh M= .195 Kg H= .9906 m (.195)(9.8)(.9906)=

1.893 J

Potential to Kinetic

Kinetic to Water Water formula= mgh .09 Kg 7 inches or .1778 m (.09)(9.8)(.1778)= 0.157 J

Water to Spring Spring formula = ½ kx2

X= .25 K= .77592 ½(.77592)(.25)2= 0.1325721 J
