PHY 125 Experiment #2: Uniformly Accelerated Motion I - Free Fall Date of Experiment: 09/14/2011 Date Submitted: 09/21/2011 Abstract: 1. Local gravitational acceleration, 2. which does not depend on mass (of steel balls) 3. Relationship b/w displacement, velocity, acceleration for a freely falling object Results "Big" Steel Ball Displaceme nt Falling Time y (m) t1 (s) t2 (s) t3 (s) avg t (s) 0.530 0.325 0.323 0.322 0.323 1. Measure the falling time of big ball for displacement of 50.0 cm. Repeat 2x & find avg time "Small " Steel Ball Displaceme nt Falling Time y (m) t1 (s) t2 (s) t3 (s) avg t (s) 0.505 0.327 0.328 0.334 0.330 2. Repeat above procedure for the small ball 3. Repeat for 5 more displacements "Big" Steel Ball Displacement Falling Time y (m) t1 (s) t2 (s) t3 (s) avg t (s) 0.398 0.288 0.285 0.286 0.286 0.530 0.325 0.323 0.322 0.323 0.600 0.351 0.349 0.350 0.350 0.700 0.378 0.378 0.380 0.379 0.834 0.413 0.412 0.414 0.413 0.956 0.443 0.442 0.437 0.441 "Small" Steel Ball Displacement...
