Items are a representative set of items for the ACP. Teachers may use
this set of items along with the test blueprint as guides to prepare students
for the ACP. On the last page, the correct answer and content SE is listed.
The specific part of an SE that an Example Item measures is NOT
necessarily the only part of the SE that is assessed on the ACP. None of
these Example Items will appear on the ACP.
Teachers may provide feedback regarding Example Items.

Two identical boxes, A and B, are resting on the floor. Box A is pulled by a rope with a force
of 50 N. Box B is pushed by a steel rod with a force of 50 N. How do the motions of the two
boxes compare and why?
A
B accelerates faster than A because steel is stronger than rope.
B
Neither box accelerates because 50 N is not enough force.
C
They both accelerate at the same rate because the forces on them are equal.
D
A accelerates faster than B because a pulling force is stronger than a pushing force.
