Julian Hart Physics 211 PY211 Lab 1 1. The data obtained in the first pre-lab helped me visualize the objects motion. The slope represents the velocity that the object. Since the slop remains constant because the best-fit line is linear means that the slope is constant through out the time and positions recorded. The Y intercept represents the initial position of the object when time is equal to zero. 2. As distance get further away from zero force gets smaller exponentially. The best fit line for this data is y = 51.371e -0.073x . The exponential best-fit line better represents the data when distance approaches infinity; however the logarithmic

Unformatted text preview: represents the data as distance approaches zero and thus they do not perfectly agree with each other. 3. The acceleration is equal to the derivative of velocity; in this case the graph of the velocity is linear so we can use the velocity to calculate acceleration. The acceleration is -1.52 m/s^2 which is not a reasonable answer compared to the acceleration of gravity which is -9.8 m/s^2. 4. To find the original velocity we used the equation from the best-fit line. The initial velocity is 3.2 m/s. 5....
