Samuel kicks a soccer ball across a grassy field and it eventually comes to a stop. If Newton’s law of inertia is true, why did the ball stop? 

• Newton’s law only applies to objects at rest. 

• The mass of the ball is not great enough to have inertia. 

• Friction with the grass applies a net force on the ball causing it to decrease its speed. 

• Gravity slowed the ball until it came to a stop.
