Given Newton's First Law of Motion, what do we reasonably expect an object to do given the following scenario. An object sits at rest with an unbalanced force acting upon it. What should we not expect this object to do? Asking another way, which of the following choices could not be an outcome?

A) The object will remain at rest.

B) The object will begin to move and then move with a constant velocity

C) The object will begin to move with a changing velocity

D) None of these answers.

    The correct answer is C) The object will begin to move with a changing velocity

    Explanation:

    Newton's First Law indicates that "Every body perseveres in its state of rest or uniform rectilinear motion unless it is forced to change its state by forces impressed upon it." This means that for a body to come out of its state of rest or of uniform rectilinear motion (where the speed is constant), it is necessary for a force to act on it.

    In Newton's first law, the forces are balanced as he perseveres in his state of rest or of uniform rectilinear motion. That is, the net force on the object is zero (that is, the result of the sum of all the forces is zero). When a force acts on a body, the body leaves its state of rest or of uniform rectilinear motion.

    Then, the correct answer is C) The object will begin to move with a changing velocity
