Answer: 1. Created or nor destroyed. 2. converted from one form to another. 3. Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces. 4. kinetic. 6. Friction, Mechanical,Thermal. 7. One way to reduce friction is to use lubricants. Friction can also be reduced by switching from sliding kinetic friction to rolling kinetic friction. Another way to reduce friction is to make surfaces that rub against each other smoother. By polishing the surface, as polishing makes the surface smooth and friction can be reduced. Using lubricants such as oil or grease can reduce the friction between the surfaces. When objects are rolled over the surface, the friction between the rolled object and surface can be reduced by using ball bearings.
