    A Newton's 1st law of motion Correct Answer Incorrect Answer
    B Joules 1st law of motion Correct Answer Incorrect Answer
    C Joules 2nd law of motion Correct Answer Incorrect Answer
    D Newton's 3rd law of motion Correct Answer Incorrect Answer

    Solution

    This phenomenon can be explained by Newton's First Law of Motion, also known as the law of inertia.  When the branch is shaken violently, the branch moves suddenly, but the leaves tend to remain in their state of rest due to inertia. This causes the leaves to detach and fall off the branch.
