Sport en verkeer
Soorten krachten:
zwaartekracht = Fz = m * g
veerkracht = Fv = C * u
schuifwrijving = Fw,s = f * Fn
rolweerstand = Fw,r = cr * Fn
luchtweerstand = Fw,l = ½ * cw * ρ * A * v2 OF Fw,l = k * v2

Evenwicht van krachten:

Fres = m * a
Nettokracht (N) = massa (kg) * versnelling (m/s2)

Δv
a=
Δt
snelheidsverandering (m/ s )
versnelling (m/s2) =
tijdsduur( s)
dv
a= = hellingsgetal raaklijn
dt

Arbeid:

W=F*s
arbeid (J) = kracht (N) * verplaatsing (m)
1 Nm = 1 J

Win + Wuit = 0
arbeid van de motor (J) + negatieve arbeid wrijvingskrachten (J) = 0

Verbrandingswarmte:

Ech = rv * V
chemische energie (J) = verbrandingswarmte (J/m3) * volume brandstof (m3)
Ech = rm * m
chemische energie (J) = verbrandingswarmte (J/kg) * massa brandstof (kg)

Brandstofverbruik:

W = Fv * s
Enuttig = η * Ein
nuttig geleverde energie (J) = rendement * energie die omgezet wordt (J)
Ein = Ech = rv * V
