The action of rubbing two surfaces together, resulting in resistance or heat, often affecting the movement of objects in contact.
A conflict or disagreement arising from differences in interests, opinions, or characteristics between individuals or groups.
The force that opposes the relative motion of two objects in contact, which can be classified into static and kinetic types based on their movement state.
Example:
摩擦でマッチに火がつくようになる。
A type of sound produced by constricting the airflow between articulatory organs such as lips, teeth, or tongue, resulting in a turbulent flow that creates a hissing or buzzing quality.
A classification of consonants in phonetics characterized by the narrowing of the vocal tract, allowing air to pass through and produce a continuous noise, exemplified by sounds like [s], [z], [f], and [ʃ].
The heat generated when two surfaces rub against each other, resulting from the resistance to motion.
The thermal energy produced due to the frictional force acting between interacting bodies in contact.
The increase in temperature that occurs as a consequence of resistance between moving or sliding surfaces.
The phenomenon where kinetic energy is converted into thermal energy during the process of friction.
A technique for training the skin, which involves rubbing the body with a dry cloth or towel to stimulate circulation and promote a sense of well-being.
A practice used in traditional Japanese health routines, where one uses a dry fabric to manually massage the skin as a means of enhancing vitality and resilience.
A skin conditioning method characterized by the use of a dry towel to create friction against the skin, intended to invigorate the body and improve its overall health.
A numerical value that represents the ratio of the force opposing the motion between two contacting surfaces to the force pressing them together, which varies based on the nature of the materials and their surface conditions.
A measurement used to quantify the resistance to movement between two objects when they are in contact, influenced by factors such as the type of friction (static, kinetic, or rolling) and the surface characteristics of the materials involved.
An essential parameter in physics and engineering that describes how easily one material can slide or roll over another, reflecting the interaction between the two surfaces and their respective physical properties.
