kontaktivoimiin
Kontaktivoimat are forces that arise when two or more objects are in direct physical contact. This contact allows for the direct transmission of forces between the surfaces of the objects. Examples of kontaktivoimat include friction, normal force, tension, and the force exerted by pushing or pulling an object.
Friction is a force that opposes the relative motion or tendency of motion between two surfaces in
These forces are crucial in everyday life and in many scientific and engineering applications. Without them,
