Question 1

dichtheid

Answer 1

ρ = m/V

M = ρ x V
V = ρ x m

Question 2

benodigde warmte & soortelijke warmte

Answer 2

Q = cmΔT

Question 3

Debiet volume/tijd & doornsee stroomsnelheid

Answer 3

Q = ΔV/Δt

Q = Av

A = π * r^2

diameter = 1/2 r (straal

Question 3

warmtestroom & warmtegeleidingscoeficient

Answer 3

P = (λAΔT)/d

Question 4

Vermogen

Answer 4

P = W/t

P = E/t

P = Fs/t

P = Fv

Question 5

resulterende kracht

Answer 5

F res = m x a

Question 6

Krachtenparen

Answer 6

F ab = - F ba

Question 7

Alle bewegingen

Answer 7

v gem = Δx / Δt

s = v * t (ook eenparig) (v = vgem)

Question 8

eenparig versneld

Answer 8

v gem = (v begin + v eind) / 2

a = Δv / Δt

Question 9

moment

Answer 9

F1 x r1 = F2 x r2

Question 10

kinetische (bewegings) energie

Answer 10

Ek = 1/2 * m * v^2

Question 11

zwaarte energie

Answer 11

Ez = m * g * h

Question 12

zwaartekracht

Answer 12

𝐹=𝑚∙𝑔

Question 13

wet van behoud van energie

Answer 13

E tot, in = E tot, uit

Question 14

Arbeid

Answer 14

W = F * s

F = W / s

s = W / F

Question 15

wrijvingsarbeid

Answer 15

W tot = ΔEk = 1/2 m * v^2 eind – 1/2 * m * v^s begin

Question 16

kWh

Answer 16

kilowattuur —> Joule : 3,6

Joule —> kilowattuur x 3,6

Question 17

rendement

Answer 17

η = E nuttig/E in

η = P nuttig/P in

Question 18

Stookwaarde chemische energie J x m-3

Answer 18

E ch = rv * V

Question 19

stookwaarde chemische energie J x kg-3

Answer 19

E ch = rm * m
