1. all of the following show friction as a useful force, except the heat energy produced when two surfaces rub together having to push a rough and heavy box across the floor to move it the friction between your feet and the floor keeping you from slipping the tread on tires the moving vehicle slow down and stop when necessary 2. if the mass of an object increases, predict what will happen to the coefficient of sliding friction. the coefficient of sliding friction will increase. the coefficient of sliding friction will decrease. the coefficient of sliding friction will stay the same. the coefficient of sliding friction will decrease by half 3. in general, the friction involved in sliding an object is (less than, greater than, or equal to) the friction involved in rolling an object. 4. what kind of friction exists between solid objects moving in water? static friction sliding friction rolling friction drag 5. select all that apply. (select all that are correct, even if it's more then one) the resistance to an object being pulled over a surface is called starting friction sliding friction static friction kinetic friction

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.
