    "abstract": "We show that relativistic dynamics can be approached without using\nconservation laws (conservation of momentum, of energy and of the centre of\nmass). Our approach avoids collisions that are not easy to teach without\nmnemonic aids. The derivations are based on the principle of relativity and on\nits direct consequence, the addition law of relativistic velocities.",
