English Danish Translational: Force Kraft Velocity Hastighed Momentum Impuls Mass Masse Rotational: Torque Drejningsmoment Angular velocity Vinkelhastighed Angular momentum Impulsmoment Moment of inertia (tensor) Inertimoment To add to the possible confusion: in both languages the term "inertia/inerti" is used to describe resistance to change of velocity (also for translational movement), and in English the term "impulse" means change of momentum during a collision.
