In this video, we see Newton's 1st law anything in motion stays in motion until a force acts on it. Here we see what might happen in a car accident if a child doesnt wear a seat. Even thought the car stop, the cild is still moving at the velocity the car had. The child kept moving until eventually, the child stop on the dashboard.
