Definition
Meaning and Definition
The static friction that needs to be overcome to set a stationary object in motion, especially between two surfaces in contact.
In engineering and physics, the force or phenomenon that prevents an object from starting to move when force is applied, often due to adhesion or cohesion between surfaces. Metaphorically, it can refer to resistance to initiating change or movement in a system.
Dialectal Variation

Usage
Meaning in Context
Business
Rarely used, except in highly technical industries (e.g., micromachines, hard drive manufacturing) to discuss product reliability or design challenges.
Academic
Common in engineering, physics, and materials science papers and textbooks to describe a specific type of frictional force.
Everyday
Virtually never used in everyday conversation.
Technical
The primary domain. Used precisely to describe the force that must be overcome to initiate motion in mechanical systems, micro-electromechanical systems (MEMS), and tribology.

Common Mistakes When Using “stiction”
- Using 'stiction' to refer to friction during motion (that is kinetic friction).
- Misspelling as 'sticktion'.
- Using it in non-technical contexts where 'resistance' or 'inertia' would be more appropriate.
FAQ
Frequently Asked Questions
It is a real, standard technical term, primarily used in engineering and physics. It is not common in everyday language.
Stiction specifically refers to the friction that must be overcome to *start* motion from a standstill (static friction). Regular 'friction' often refers to kinetic friction, which occurs during motion.
In very technical contexts, it can be used informally as a verb (e.g., 'The parts stiction together'), but the noun form is vastly more common and standard.
Usually, it is an undesirable effect in machines as it causes jerky starts, wastes energy, and can lead to wear. However, in some applications like brakes or clutches, a certain level of static friction is necessary for function.
The static friction that needs to be overcome to set a stationary object in motion, especially between two surfaces in contact.
Stiction is usually technical/formal in register.
Stiction: in British English it is pronounced /ˈstɪkʃ(ə)n/, and in American English it is pronounced /ˈstɪkʃən/. Tap the audio buttons above to hear it.

Mnemonic
Think of a heavy drawer that's **stuck** until you give it a strong initial tug. That initial 'stuck' resistance is **ST**atic fr**ICTION** = STICTION.
Conceptual Metaphor
INITIAL RESISTANCE IS STATIC FRICTION (e.g., 'The stiction in the committee's old habits prevented any new policy from getting started.').
