Unitatea 2 eta 3

Question 1

Lana

Answer 1

F= d x Ar x cos 0 JOule

Question 2

Potentzia

Answer 2

P = W/t aldiuneko potentzia P=F x v

Question 3

Energia

Answer 3

W osoa = AEz
W konts= -AEp

Question 4

Answer 4

Wez konts = AEm

Question 5

indar baten momentua

Answer 5

M= F x r x sin 0

Question 6

Inertzia momentua

Answer 6

I = mr²
Ez = 1/2 x I x w²

Question 7

Grabitazio unibertsalaren legea

Answer 7

F = G(m1m2)/r²

Question 8

Eremu grabitatorioaren intentsitatea

Answer 8

g=F/m2= Gm1/r²

Question 9

Energia Potentzial Grabitatorioa

Answer 9

(Atik Bra) Wkonts= -AEp
= Epb - Epa = G(m1m2)/rb² -G(m1m2)/ra²

Question 10

Potentzial grabitatorioa

Answer 10

V=Ep/m2= -Gm1/r
Wkonts= -AEp= -m(Vb-Va)
