Discussion: 1. Explain why your velocity vs time graph should be a straight line. 2. Why should the slope your velocity vs time graph be equal to the acceleration due to gravity, g? 3. Compute the uncertainty in your measurement using the following equation: 2 2 δχ ² √ ( 4² ) ² + (²) ². 6g= 8 and report your result as g±6g. Refer back to "Measurement and Density" laboratory, if needed, for a discussion on computing the uncertainty in a measurement. You will have to explore lahquest to determine how these quantities are handled by the program. 4. We do not see feathers and baseballs fall at the same rate on Earth's surface. Why? I
5. Discuss the possible sources of error in your measurement. Specifically, what are some sources of systematic error? 6. Why don't we calculate the instantaneous velocity as AX-1 Алл-1 why do we use Eq. (4) instead? Vn or V₁ = Ag = 8alt 8 = GME 7. The value of g you obtain in this experiment is accurate at sea level however as you increase in altitude the value of g decreases the change in g. Ag or the change in g for a given altitude is given by the following equation AX+1, Aintl.n 1 (R+h)² (R)² I Where G is the universal gravitation constant, Me is the Mass of the earth, R is the average radius of the earth and h is the altitude above sea level. We will calculate Ag to determine the required resolution to measure differences in altitude from large altitudes to small altitudes, use the equation above to complete the table of given altitudes.
