Someone plz help. Friction is a contact force that resists the sliding motion between two objects that are touching. The force of friction acts in the opposite direction of the motion. Rougher surfaces produce greater friction than smooth surfaces. Other factors, such as the weight of an object, also affect the force of friction. Newton suggested that objects, like a soccer ball, have a natural tendency to keep moving. The only reason they stop, he believed, is because an unbalanced force act on them. By an unbalanced force, Newton meant the force applied to the soccer ball by its environment. When kicked, the surface of the ball travels over the grass, creating friction. The taller the grass, and the rougher the surface of the ball, the more friction is created. And the more friction that exists between the ball and the grass, the less it will travel after being kicked. Now, imagine that there is no grass. Instead, the ball is resting on a frozen lake. When you kick the ball on the ice, the ball will go much farther than it would have on the grass. This is because ice provides a lot less friction than the grass. Using the text above, provide an example of how friction can be reduced in this sport
