Lab A2 – Investigating Uniform Acceleration Problem 1: What is the shape of the position – time graph for an object travelling with uniform acceleration? Table 1: |Time (s) |Position (cm) | |0.00 |0.00 | |0.100 |1.22 | |0.200 |3.37 | |0.300 |6.73 | |0.400 |11.21 | |0.500 |16.90 | |0.600 |23.60 | |0.700 |31.56 | |0.800 |40.52 | |0.900 |49.99 | Graph 1: The shape of the position-time graph for an object travelling with uniform acceleration is an exponential (curved upwards) shape. Problem 2: What is the shape of the velocity – time graph for an object moving with uniform acceleration? Sample Calculation: [pic] Table 2: |Tmid (s) |Vavg (cm/s) | |0.050 |12.20 | |0.150 |21.50 | |0.250 |33.60 | |0.350 |44.80 | |0.450 |56.90 | |0.550 |67.00 | |0.650 |79.60 | |0.750 |89.60 | |0.850 |94.70 | Graph 2: The shape of the velocity-time graph for an object moving with uniform acceleration is linear. [pic] [pic] [pic] Evaluation: 1. The air puck was spinning as it was sliding down the platform so that could’ve effected the acceleration and speed of the puck so that could’ve impacted the overall set of data and the accuracy. 2. The air puck slightly shifted to the right as it was sliding down the platform and that could’ve impacted the average velocity and the accuracy of the data by increasing the friction acting against the puck. 3. An uneven platform may have impacted
