Wetten van Newton
1. Kracht (F -> N) = Massa (m -> Kg) x versnelling (a -> m/s 2)
Kracht (F -> N) = Massa (m -> Kg) x verticale valversnelling (g -> m/s 2 = 9,81m/s2)
2. Massa is traag
3. Actie = - reactie
Moment (M -> Nm) = Kracht (F -> N) x Arm (d -> m)
Massa(m)
Dichtheid () =
Volume(V )
Volume Kubus (V) = Lengte (l) x breedte (b) x hoogte (h) = Oppervlak (A) x hoogte (h)
Oppervlak cirkel (A) = x radius (r)2
o ±3
Inertia is de mate van weerstand die een lichaam biedt om te bewegen
o Inertia (I) = Massa (m) x Radius (r) 2
1 Ampère = 1 Coulomb per seconde
1 Volt = 1 Joule per Coulomb
1 Watt = 1 joule per seconde
