Samenvatting Natuurkunde
Hoofdstuk 2 en 3
Hoofdstuk 2 sport en verkeer
Belangrijke formules en letters hoofdstuk 2:

Eenparige beweging geldt:
s=vxt
 s = afstand in M, v = constante snelheid in m/s, t = tijd in seconde

Niet constante snelheid:
s = Vgem x t

in x,t-diagram  vgem = Δx/Δt

Versnelling:
a = Δv/Δt
 a = versnelling in m/s, Δv = de snelheidsverandering in m/s, Δt = tijdsduur

Gemiddelde versnelling:
agem = Δv/Δt
 a is in m/s2

Versnelling op bepaald tijdstip:
a = (Δv/Δt) raaklijn
 a is in m/s2

in x,t-diagram  v=(Δx/Δt) raaklijn

Tweede wet van newton:
Fres = m x a
 fres = de netto kracht in N, m = de massa in kg, a = versnelling in m/s2

vrije val versnelling zonder luchtweerstand:
Fz = m x g
 g = 9,81 m/s2

Belangrijke formules en letters hoofdstuk 3:

Dichtheid:
p = m/V
 p = dichtheid in kg/m3 of kgxm-3, m = massa in kg en V = het volume in m3. (Volume is
hoogte x breedte x lengte).


Warmte en temperatuursverandering:
Q = c x m x ΔT
 Q = warmte (energie) in J, c = de soortelijke warmte, m = de massa in kg en ΔT = temp.
Verschil.

Warmte stroom:
P = λ x A x ΔT/ d
 P = warmte stroom, λ = warmtegeleidingscoëfficiënt, A = oppervlakte van de wand in
m2, ΔT = temp. Verschil en d = dikte van wand in m.
