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
