| Student Manual |  This experiment investigates the principle of energy conservation through the collision of two objects moving in two dimensions. Students will get familiar with the concept of translational collision and will probe the elasticity of a collision. The experiment also provides ample practice in calculating uncertainties and relative errors. |
