Directions:
Today you will be taking the Ohio Physical Science Practice Assessment.
There are several important things to remember:
1.
Read each question carefully. Think about what is being asked. Look
carefully at graphs or diagrams because they will help you understand
the question. Then, choose or write the answer you think is best in your
Answer Document.
2.
Use only a #2 pencil to answer questions on this test.
3.
For questions with bubbled responses, choose the correct answer and then fill
in the circle with the appropriate letter in your Answer Document. Make
sure the number of the question in this Student Test Booklet matches the
number in your Answer Document. If you change your answer, make sure
you erase your old answer completely. Do not cross out or make any marks
on the other choices.
4.
For questions with response boxes, write your answer neatly, clearly and
only in the space provided in your Answer Document. Any responses
written in your Student Test Booklet will not be scored. Make sure the
number of the question in this Student Test Booklet matches the number
in your Answer Document.
5.
If you do not know the answer to a question, skip it and go on to the
next question. If you have time, go back to the questions you skipped
and try to answer them before turning in your Student Test Booklet and
Answer Document.
6.
Check over your work when you are finished.

2. Which statement describes an interacting force pair?
A. The force exerted by a cyclist equals the combined forces of friction and air
resistance.
B.
A car exerts a force on a bug as they collide, and the bug exerts an equal
force on the car.
C. Gravity exerts a downward force on a refrigerator, and the normal force
pushes up on the refrigerator.
D. Two people pull on opposite ends of a rope, but the rope does not move
because the people pull with equal forces.
