When a soccer ball is rolling along a grassy field, it does not
continue moving forever. What force is acting upon it to change its
state?

As the soccer ball rolls across the grassy field, it’s met with friction from the grass, which is a major force acting against its motion. This frictional force slows down the ball due to the interaction between the grass and the ball’s surface, gradually reducing its speed until it eventually comes to a stop.

In addition to friction, gravity plays an essential role in keeping the ball grounded. It pulls the ball toward the Earth’s surface, ensuring that it maintains contact with the ground as it rolls. Without these forces at play, the ball would glide without restraint, but thanks to friction and gravity, the ball’s adventure is kept in check!
