Question

List three ways of reducing friction.

Answer 1

Friction is defined as the resistance experienced by the surface or by an object when it is moved over or has the tendency to move over another surface.

Methods to reduce friction

1. Streamlining in order to reduce the friction between the body and surrounding fluid.
2. Polishing the surface, as polishing makes the surface smooth.
3. Applying lubricants such as oil or grease on the surfaces.
