Linear-motion bearing - Wikipedia
A linear-motion bearing or linear slide is a bearing designed to provide free motion in one direction. There are many different types of linear motion bearings.
Motorized linear slides such as machine slides, X-Y tables, roller tables and some dovetail slides are bearings moved by drive mechanisms. Not all linear slides are motorized, and non-motorized dovetail slides, ball bearing slides and roller slides provide low-friction linear movement for equi…Wikipedia · CC-BY-SA 许可下的文字- 预计阅读时间：9 分钟
直線運動 - 维基百科，自由的百科全书
- 物体的所有粒子在同一时间内通过相同距离的运动称为平移运动。平移运动分为两种：直线运动、曲线运动。由于直线运动是单一维度的运动，因此物体在特定方向上移动的距离和位移相同。位移的国际单位制单位是米。如果x 1 {\displaystyle x_{1}} 是物体的起点，x 2 {\displaystyle x_{2}} 是终点，那么位移由下式得出： Δ x = x 2 − x 1 {\displaystyle \Delta x=x_{2}-x_{1}} 位移在旋转运 …
Straight-line mechanism - Wikipedia
A straight-line mechanism is a mechanism that converts any type of rotary or angular motion to perfect or near-perfect straight-line motion, or vice versa. Straight-line motion is linear motion …

2024年8月13日 · The motion of a point particle is fully described using three terms - position, velocity, and acceleration. For real objects (which are not mathematical points), translational …
Linear motion | Newton’s Laws, Acceleration, Velocity | Britannica
Linear motion, motion in one spatial dimension. According to Newton’s first law (also known as the principle of inertia), a body with no net force acting on it will either remain at rest or …
Equations of motion - Wikipedia
In physics, equations of motion are equations that describe the behavior of a physical system in terms of its motion as a function of time. [1] More specifically, the equations of motion describe the behavior of a physical system as a set …
