ngẫu lực

Friendly

The Vietnamese word "ngẫu lực" refers to the concept of a "couple" in physics. It describes a pair of forces that are equal in size, but opposite in direction, and are applied at different points on an object. This creates a rotational effect, causing the object to spin or twist around a point.

Usage Instructions

• "Ngẫu lực" is primarily used in the context of physics and engineering when discussing mechanics and forces.
• It is important to understand this term when learning about rotational dynamics or torque in physics.

Example

• Simple Example: If you use a wrench to tighten a bolt, the force you apply at one end of the wrench creates a "ngẫu lực" that helps turn the bolt at the other end.

Advanced Usage

• In more advanced physics discussions, "ngẫu lực" can be involved in calculations related to torque (mô men xoắn), where the magnitude of the forces and the distance from the point of rotation are considered.
• Example in an advanced context: "Khi tính toán mô men xoắn, chúng ta cần xem xét độ lớn của ngẫu lực và khoảng cách giữa các lực."

Word Variants

• "Ngẫu lực" does not have direct variants but is closely related to terms like "mô men xoắn" (torque) and "lực" (force).

Different Meanings

• While "ngẫu lực" specifically refers to the concept of a couple in physics, it does not have other meanings in everyday language. It is a technical term primarily used in scientific contexts.

Synonyms

• There are no direct synonyms for "ngẫu lực" in Vietnamese, as it is a specific term.
