Question

Which of the following is a reasonable conclusion concerning the measurements of g from the two experiments? (The experiment of the dropped ball and the experiment of the ball thrown upward) a- The measured value of g from the two experiments agree with each other. b- In one experiment, the air resistance increases the observed acceleration (magnitude) and in the other experiment air resistance decreases the observed acceleration (magnitude). c- No two experiments yield the exact same measured value. (The accepted value of g has been determined by making countless measurements using an average value.) d- b and c, but not a

Explanation / Answer

b- In one experiment, the air resistance increases the observed acceleration (magnitude) and in the other experiment air resistance decreases the observed acceleration (magnitude).
