Reyna kicks a ball, which then rolls across a grassy field. which is the best explanation for why the ball eventually comes to a stop? a. the force of gravity pulls the ball down into the grass until it can no longer move b. the force of friction between the ball and the grass slows the ball to a stop. c. the force from air resistance slows the ball to a stop. d. a force is not necessary because all things naturally come to a stop.

Which sentence best describes the passage? pick one of the bold sentences. friction is a force that opposes the motion of an object. friction occurs when a solid, liquid, or gaseous substance comes into contact with another substance. the result of friction is a force that opposes the motion of an object or substance. in other words, the motion of an object or substance slows down when there is friction. friction converts kinetic energy (energy of motion) into heat. one type of friction is called rolling friction. rolling friction is a restrictive force that slows the motion of a rolling ball. rolling friction occurs when a round object rolls on a surface. this friction will cause the object to stop rolling eventually. the amount of friction produced depends on the material of the object and the makeup of the surface touching it. for example, a wooden bowling lane is oiled to reduce the amount of rolling friction that occurs when a bowling ball is thrown during a game. otherwise, rolling friction might slow the ball enough to prevent it from knocking over any bowling pins.
