Understanding Momentum in Two Dimensions

❌ Assuming angle between paths is always 90° for any masses. ✅ Fix: The 90° rule applies only when both masses are equal and the target is initially at rest. 2d Collisions Gizmo Answer Key Activity C

In introductory physics, most collision problems are confined to a straight line (1D). However, the real world happens in two or three dimensions. The allows students to experiment with pucks on an air hockey table to see how momentum and kinetic energy behave when objects collide at an angle.
