  • Next message: Clive Grainger: "Re: [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
