Notice that the acceleration, the centripetal acceleration is linear in r.

在此注意，向心加速度与r是成正比的。

Acceleration starts in the linear accelerator, the power is so high that sometimes lightning strikes right in this room.

加速器的起端是直线加速器，需要的能量是如此之高，有时候这房间内会发生雷击闪电。

For measuring rotary acceleration this material can be in the form of a disk, for linear acceleration it is formed as a strip of metal (see picture on top).

旋转加速度测量这种材料可以在一个磁盘的形式，线性加速把它当作金属带组成(见上面图片)。

They also calculated impact dose injury risk parameters common to laboratory and on-field traumatic neuromechanics: linear acceleration, angular acceleration, angular velocity, Gadd Severity Index, diffuse axonal injury, acute subdural hematoma, and brain contusion.

As sighted drivers do, Mark made active use of his other senses such as sound, listening to the noise the tires generate rolling over the roads, and used the sense of angular and linear acceleration perceived from his inner ear to make judgments and adjustments to the controls of the vehicle.

Freespace Sensor Modules are used by engineers to add inertial motion control to a product without having to learn about motion sensing or MEMS. These compact modules, the smallest of which is 9mm x 19mm x 2.5mm, are pre-calibrated for mass production, provide a well-documented API for interpreting motion, and provide data such as cursor position, linear acceleration, angular position, and angular velocity to enable the creation of novel applications.
