Transcript of Behoud van Energie- Vermogen- rendement

fysica H3
Behoud van Energie- Vermogen- rendement
wet van behoud van energie
totale energie = constant
vermogen (p)
formule: arbeid (w) / verschil in tijd (delta t)
Grootheid: rendement
eenheid: èta



formule: Enuttig/Etotaal *100%
mechanische energie
mechanische energie= pototentiele energie + kinetische energie
potentiële energie: Epot
kinetische energie: Ekin
mechanische energie: Emech
warmte energie:Eth (thermische energie)
eenheid
1Watt (W) = 1Joule per seconde
(J/s)

1kiloWatt (kW) = 1000 J/s

1megaWatt (MW) = 1.000.000J/s
menselijk hart = 1,5W
paard = 520W
auto = 750W-1,5MW
locomotief = 220kW-2,2MW
vliegtuigmotor = 7,5MW
kerncentrale = 400MW
lancering space shuttle = 350MW
grootheid energie : E
quiz
is er een verschil tussen

W= 54J

E= 54W
ja



W1=arbeid
W2=Watt
vraag 2
is er een verschil tussen bewegingsenergie en kinetische energie?
NEE
doordenker
klopt deze formule Epot=Emech-Ekin
nee ze is fout
echte formule: Emech=Epot-Ekin

afleiding Epot= Ekin-Emech
