PRE-LAB QUESTIONS 1. What is the acceleration of a ball that is vertically tossed up when it reaches its maximum height? 0 m/s 2. If you drop a ball, and then one second later drop a ball identical in mass, size and shape, what happens to the distance between them as they fall? One hits the ground faster than the other the distance should stay roughly the same until that. 3. What does a positive and negative slope represent for a velocity versus time graph? The positive is time spent actually moving at a positive velocity, the negative is the time spent stopping ©eScience Labs, 2018 1-D Kinematics
EXPERIMENT 1: DISTANCE OF FREE FALL Data Sheet Table 1. Washer Free Fall Data Trial Drop Height (m) Time (s) 1 0.8 0.79 2 0.6 0.49 3 0.4 0.04 Average 0.44 Auditory Observations of Equally Spaced Hex Nut Pattern: Auditory Observations of Unequally Spaced Hex Nut Pattern: Post-Lab Questions 1. Record your hypothesis from Step 1 here. Use evidence from your results to explain if your hypothesis was supported or not. I believed that all drop heights would’ve sounded the same but that was wrong. 2. What was the difference between the noise patterns for equally spaced hex nuts compared to the unequally spaced hex nuts? ©eScience Labs, 2018 1-D Kinematics
It’s louder when dropped from higher places. 3. What caused the differing noise patterns? The height difference from each drop. 4. Define the independent and dependent variables in the experiment. Independent was the catch pan and the dependent was the distance of each drop. ©eScience Labs, 2018 1-D Kinematics
