Next message: MTweedy@aol.com: "[Channel-talkforce] force and motion questionnaire"
A particpant who teaches 9th grade science has questioned the correct answers
to the pretest for item numbers: 2, 8, and 9.
He says item # 2.'s answer should be d. - that none of the above are correct;
# 8.'s answer should be a. - that the windshield exerts a greater force on
the bug than the bug exerts on the windshield, and that # 9.'s answer should
be that the small car exerts a greater force on the truck than the truck
exerts on the car.
Please explain the correct answer choices.
Thanks, Mary Tweedy
