smooth

Definition

Smooth means that something has a surface that is free of bumps or roughness. It can also mean that something is easy to move or slide over.

In science, smooth can be used to describe the surface of objects or materials. For example, a mirror is smooth because it has a surface that is free of bumps or roughness. A ball bearing is also smooth because it has a surface that is easy to move or slide over.

Smooth surfaces are often used in science because they can help to reduce friction. Friction is the force that opposes the movement of two surfaces that are in contact with each other. Reducing friction can help to improve the efficiency of machines and devices.
