A shadow can be called a projection, if you are discussing the way one shape can be transformed into another as a shadow.

The edge formed by two surfaces meeting each other is called a "corner" or a "boundary."
On a topographic map, relief is the representation of the shapes of hills, valleys, streams, and other terrain surfaces as depicted by the mapmaker.
When solid surfaces rub against each other, this friction is called dry friction. It is the force resisting the relative motion of solid surfaces, such as two objects sliding against each other.
The friction between moving surfaces is called kinetic friction. It occurs when two surfaces are in contact and move relative to each other, causing resistance to their motion.
When two surfaces rub against each other, it is called friction. Friction is the force that resists the motion of one surface over another.
It is called abrasion when the surfaces of soiled materials scraps and grinds against each other. This process can lead to wear and tear of the materials involved.
The kind of friction that occurs when solid surfaces slide over each other is called kinetic friction. It is the resistance between the surfaces that are in motion relative to each other.
The force that occurs between surfaces in contact with each other is called friction. Friction is a resistance force that acts in the opposite direction to the motion or tendency of motion between two surfaces. It can be static (between stationary surfaces) or kinetic (between moving surfaces).
The force caused by surfaces rubbing against each other is called friction. Friction acts in the opposite direction of the force applied and resists the motion between the surfaces.
Animals which live on the surface of other animals are called parasites.
The force that resists the motion of objects or surfaces as they move over one another is called friction. It occurs due to the interactions between the surfaces of objects in contact with each other.
