Answer

The best answer is **D. he is correct because unbalanced forces can change speed or direction.**<br /><br />Newton's First Law of Motion states that an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This means an unbalanced force is *required* to change either the speed or the direction of a moving object.<br />
