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 Wind formula- (d)()()(C) Density of

air=0.00012041 Turbine diameter= .0762 Velocity= 2.4 Constant=.005 (0.0012041)() (.005)= .000483 J

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 KineticWater Bottle Kinetic = ½ mv2

M=.105 Kg V=.1778/.94= .189

m/s K=.5(.105)= .002 J

Hammer

Formula= ½ (I) I= 1/3m W= ½ (80.613) (3.342) = 449.6 J

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

Water = mgh m= .09 Kg g: 9.8 h= .1778 m .09(9.8)(.1778)= 0.1568196 J
