a) Gravity

b) Inertia

c) Friction (highlight your answer)

The Role of Friction in Stopping a Wagon

The most likely reason for the wagon to stop is due to **friction**. When a child rides a wagon down a hill, the wagon's wheels are in constant contact with the ground. The friction between the wheels and the ground resists the motion of the wagon, gradually slowing it down until it comes to a complete stop.

Understanding Friction in Motion

Friction is a force that opposes the relative motion or tendency of such motion between two surfaces in contact. In the case of the wagon going down a hill, the friction between the wheels of the wagon and the ground plays a crucial role in bringing the wagon to a stop.

As the wagon moves, the friction between the wheels and the ground creates a resistance force that acts opposite to the direction of the motion. This force gradually decelerates the wagon until it stops moving entirely.

While other factors like gravity and inertia also influence the motion of the wagon, friction is primarily responsible for the wagon coming to a stop. It is important to consider the presence of friction in various scenarios involving motion to understand how it affects the movement of objects.
