AP Physics Experiment – Collision in Two Dimensions Purpose To determine whether energy is conserved in a two-dimensional collision Procedures 1. Level the air table. Tape the corners of a sheet of carbon paper with the black side up on the glass surface of the air table. 2. Place a sheet of recording paper on top of the carbon paper. Press lightly on the paper to remove any air pockets. 3. Select two pucks of approximately equal mass. Measure and record the mass (kg) using an electronic balance of each puck (m 1 and m 2 ). 4. Place both pucks on the paper and check that the chain extending from each air hose is inserted into the receptacle on each puck. 5. Position one puck stationary at the center of the table and the second puck at a 90 o angle with respect to the diameter of the first puck in order to generate a direct head-on collision. 6. Set the spark timer from 10-100ms. [Note: For most collisions, a setting of 50ms generates a suitable number of dots]. Measure and record the spark timer interval setting (t). 7. Turn on the air compressor. Practice several trial runs of the collision such that the impact occurs at the approximate center of the paper. 8.
