Question
(30 points) Part 3 A free fall experiment to determine the acceleration due to gravity gives the m/s and following g values: g i = 1 1 m/s-82= 10 m/s-83 = 10.2 m /s-8,-9.26m/s2.35 = 10 Percent variation = 6.16 % Percent difference = 2.98 % A. Based on the information above, how precise is the acceleration due to gravity measurement?? B. Based on the information above, how accurate is the acceleration due to gravity measurement?? Conceptual Questions A. By how much does the speed of a freely falling object change each second of the fall? B. If air resistance is neglected, how does the acceleration of a ball that has been tossed straight upward compare with its acceleration if it is simply dropped?. C. One ball is thrown straight up in the air and another is just dropped from rest. which velocity graph best represent the motion of the two balls? ?Explanation / Answer
(A) The speed of an object falling freely increases by 9.8m/s per second.
(B) The acceleration of the ball remains the same in both the cases and is equal to the gravitational acceleration.
