A 2 kg mass: the force to move it, the energy it carries
physical
Newton's second law fixes the force to accelerate a mass; its kinetic energy fixes what the motion is worth. Same mass, two laws, both checked. Worked & sealed by the engine — F = m·a = 2·5 = 10 N · KE = ½·m·v² = ½·2·3² = 9 J. [HOLDS; open the seal to re-check.]
