Question 4

7 points total Distribution of points

(a) 1 point

For sketching only one force pointing straight down from each sphere and indicating that this force represents the force of gravity

1 point

(b) 1 point

For sketching a horizontal line at zero velocity for sphere A, and sketching a horizontal line at some non-zero velocity for sphere B

1 point

For indicating that the difference in horizontal motion does not affect the vertical motion of the spheres

1 point

For indicating that both spheres start with the same vertical velocity 1 pointFor indicating that both spheres have the same vertical acceleration 1 point For indicating that falling the same height would take the same time 1 pointFor no incorrect or irrelevant statements 1 point

AP® PHYSICS 1 2015 SCORING COMMENTARY

Question 4 Overview The intent of this question was to assess the level of student understanding of 2D motion by describing in words (a coherent paragraph) and equations the physics behind one ball dropped from rest and a second identical ball projected with an initial horizontal velocity from the same height.

Sample: P1Q4 A Score: 7 This concise, accurate, and clearly written response that fully answers the question earned full credit.

Sample: P1Q4 B Score: 5 Part (a) and part (b) earned full credit, for a net of 2 points. The response to part (c) earned 3 points. It does not say that both spheres have the same initial vertical velocity and does not indicate that the acceleration of both spheres is the same. It is mentioned that the force on each sphere is the same, but this is not connected with the acceleration.

Sample: P1Q4 C Score: 2 Part (a) earned no credit, since there is an extra force drawn. Part (b) earned 1 point for full credit. Part (c) earned 1 point stating that the acceleration is the same for both spheres. Stating that “gravity affects them both differently” lost the ‘no incorrect statement’ point.
