Answer: objects in motion tend to stay in motion unless acted upon by an outside force.
Explanation:
We know from Newton's first law, an object tends to be in state of rest or motion unless and until an external unbalanced force acts on it. In the given situation, the sudden break stops the car but since there is nor force acting on the teddy bear, it has tendency to move forward. Thus, until it the teddy bear hits the dashboard, it doesn't stop.
