A substance applied to a surface to reduce friction is called a lubricant. Lubricants help to reduce the friction between two surfaces in contact, allowing them to move more smoothly against each other.

A substance or material that reduces friction is called a lubricant. Lubricants are applied between surfaces in motion to decrease friction and wear, allowing for smoother movement and reduced heat generation.
The friction that occurs when an object rolls over a surface is called rolling friction, not round friction. Rolling friction is typically less than sliding friction because the object's motion is smoother and involves less resistance from the surface.
When an object rolls over a surface, the friction that occurs is called rolling friction. Rolling friction is lower than sliding friction, which occurs when an object slides along a surface. Rolling friction results from the deformation of the object and the surface it is rolling on.
The friction that occurs is Rolling Friction
The friction that exists between a surface sliding on another surface is called kinetic friction. This type of friction occurs when two surfaces are in relative motion.
