Explanation:
Newton's First Law of Motion:
- According to Newton's First Law of Motion, an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an external force.
- When the car starts moving in the forward direction, the boy inside the car is also set in motion along with the car.
Reference Frame:
- The boy's reference frame is the interior of the car.
- When the car accelerates forward, the boy tends to remain at rest due to inertia in his reference frame.
Experiencing a Backward Force:
- Since the boy is in the car which accelerates forward, his body tends to stay in its current state of rest.
- Due to this, the boy experiences a backward force relative to the car's direction of motion.
- However, this backward force is not an actual force acting on the boy; it is simply his body's resistance to the forward acceleration of the car.
Therefore, when the driver suddenly starts moving the car in the forward direction, the boy inside the car does not experience a backward force.

According to Newton's first law of motion (the law of inertia), an object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and direction unless acted upon by an external force. When the driver starts moving the car in the forward direction, the boy in the back seat would also move in the same forward direction. The boy would experience a forward force due to the car's acceleration, not a backward force. Therefore, the boy would not experience a backward force in this scenario, so the statement is false (never).
