Did the sphere in the experiment always land exactly where predicted? If not, why was there a difference between the distance calculated and the distance measured? The spheres didn’t land at the spot as predicted. The difference is due to the non
-
inclusion of air resistance to the motion of the sphere which can cause resistance to the motion of the ball, reducing it. 2.
Why is it important to use the grooved ruler to ensure that the sphere leaves the table in a horizontal direction? It is important to use the grooved ruler to ensure that the sphere leaves the table in horizontal direction, so we don’t have any miscalculations in our readings for each trial. 3.
If the same experiment were performed on the moon, what would be different? The Sphere would have different gravitational force on the moon 4.
What is different about the vertical component of the sphere’s velocity and the horizontal component of the sphere’s velocity once the sphere leaves the table?
The vertical aspect remains constant upon leaving the table 5.
If the same experiment were repeated with the same angles, but from a taller table, how would the results change?
The vertical element would vary, consequently altering the overall computed
distance.
