网络扩展资料
Rotational inertia（旋转惯量）, also known as moment of inertia（转动惯量）, is a physical quantity that describes an object's resistance to rotational motion around a specific axis. It depends on the object's mass distribution and the distance of each mass element from the axis of rotation.
Rotational inertia can be calculated using the following formula:
$I = sum m_i r_i^2$
where $I$ is the rotational inertia, $m_i$ is the mass of each element, and $r_i$ is the distance of each element from the axis of rotation.
Rotational inertia plays an important role in many physical phenomena, such as the motion of a spinning top or a rotating planet.
Example sentences
- The rotational inertia of a cylinder is greater than that of a sphere with the same mass and radius.（圆柱的旋转惯量比同样质量和半径的球体大。）
- The gymnast increased her rotational inertia by extending her arms during the spin.（体操运动员在旋转过程中伸展手臂增加了旋转惯量。）
Usage
Rotational inertia is a fundamental concept in classical mechanics and is used in the analysis of various objects and systems that involve rotational motion, such as wheels, gears, and flywheels. It is also used in engineering applications, such as the design of engines and turbines.
Synonyms
- moment of inertia（转动惯量）
Antonyms
- translational motion（平移运动）
