Question

the vehicle is traveling at a constant speed down the street. the car applies the brakes for an abrupt stop and the box that isnt tied down goes flying forward. 1 explain why the box continued to fly and did not stop with the vehicle.

Explanation:

The box has inertia. According to Newton's first - law of motion, an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force. When the car stops, no force acts on the box immediately to stop it, so it continues moving forward.

Answer:

The box has inertia. Due to Newton's first law, as no force acts on the box to stop it immediately when the car brakes, it continues moving forward.
