The primary lesson of in the 2D Collisions Gizmo is that the center of mass of a system is "the boss"—it moves in a straight line at a constant speed, completely unaffected by the chaos of the collision between the individual pucks . The Core Concept: Center of Mass
In a 2D collision, momentum is conserved: A) Only in the x-direction B) Only in the y-direction C) Independently in both x and y directions Answer: C 2d Collisions Gizmo Answer Key Activity C
Two pucks collide and stick together. Puck A has mass 1.5 kg moving at 3.0 m/s at 0°. Puck B has mass 2.5 kg moving at 2.0 m/s at 90° (straight up). The primary lesson of in the 2D Collisions
